Question: Hi Doc,

I am a male and I recently got an oral job (BJ) from a stripper. This happened for around 15 min. What are the odds for getting any STD's like HIV, Syphilis or any other disease? When should I get any tests done (If required)?

Note: I am not sexually active since 2 years and this is the first time I got it from a stripper

Thanks for the query. I apologize for the delayed response.

1. Risk of STD's and HIV following an unprotected sexual intercourse varies.
a) It has very minimal to almost no risk of HIV transmission. Only if the performer's saliva is contaminated with blood and if you have mild abrasion on your genital organs this possibility exists. So you need not worry about this.
b) Regarding STD also, the receiver of oral sex is more at risk than the giver. If the performer has some lesion in the mouth like ulcer or vesicles, then there are chances for the same to be transmitted. Otherwise oral sex is comparatively safer than penetrative sex.

2. Regarding the testing, I recommend all my patients with history unprotected exposure with an unknown partner to go through testing once after 12 weeks. This is to make sure that we rule out the very remote possibility.

In brief, I do not foresee any serious implication from your current encounter. However I do suggest testing after 12 weeks. And please always practice safe sex with unknown partner.

Hope this answers your query. Let me know if I can assist you with any other queries.

Hi Doc, Thank you for your response.Just couple of more questions

a) Does performing Cunnilingus on a woman having HIV transfer the diseases to the performer? What are the odds?

b) What are the chances of HIV when someone lick woman breasts? When is it transferred?

I am asking you in order to be safe from next time around. I apologize if I did not frame these questions properly. Thank you

Welcome back with your feed back questions.

Estimated Per-Act Probability of Acquiring HIV from an Infected Source, by Exposure Act

Type of Exposure       Risk per 10,000


Blood Transfusion       9,000 b
Needle-sharing during injection drug use      67 c
Percutaneous (needle-stick)       30 d

Receptive anal intercourse       50 e, f
Receptive penile-vaginal intercourse      10 e, f, g
Insertive anal intercourse       6.5 e, f
Insertive penile-vaginal intercourse       5 e, f
Receptive oral intercourse       low e, i
Insertive oral intercourse       low e, i

Even with insertive sexual exposure, the risk is only 5 out of 0000 only. Receptive oral sex, the risk is very low even in case of felatio. With cunnilingus the risk is almost nil.
Similarly licking of breast is not at all risky for HIV. If she is a lactating woman then there may be very low infectivity, if the act continues for months.

This information will help you to save guard yourself in future.

Good luck to you.

A few months ago i got a terrible rash on my face. This morning I woke up and the rash had returned. The skin around my nose feels thick and itchy, the skin on my cheeks around my nose turns red and swollen and my lips swell out and become very itchy and burn slightly. Last night i did use poppers quite a bit. I have used poppers in the past, and never had this reaction. However I get the feeling that these poppers which we bought are sub-standard and I have developed an allergic reaction to them. Several months ago I was treated for syphilis after being in China, and my immune system took a knock. It was after that time which I had my first reaction to poppers, this is the second time. What can I use to calm the skin

I had unprotected sex with my new girlfriend about 4 weeks ago, the first week I used sulfur soap by accident on that area when the skin was still recovering from use. I got a horrible irritation but now it is gone. The discomfort came back, and for a few days I had pain that came and went on my testicles and on my glans. Now the testicle pain is gone, but the discomfort continues on my penis, the skin seems to be different and after masturbation the skin looked extremely wrinkled and silky with a few red dots. I got checked for Chlamydia, Syphilis, HIV, and gonorrhea Last week and all the results were negative. I have had a shifting discomfort in that area for a while now and I have been wondering what I have? My penis feels like it has something, I have no pain during urination and I don't think I have had random discharge either.

i ve had a macular rash for 32 days now. everywhere but where my bikini bathing suit covered. It has faded only on chest, shoulders and upper back but remains every where else. I also have EXTREME SKIN MOTTLING on arms/legs. Skin biopsy showed phototoxic cells/sunburned cells and cell death. I have a positive ana, high rf factor, fatigue, excessive thirst, muscle weakness. I got sun exposure while in treatment for Xanax/opiates dependency and was detoxed for about 30 days. I was also taking vistaril, busbar, ibersarten while in treatment. tested for syphilis, hep panel, both non reactive. could this be lupus or even cancer (lymphoma?) Seeing a rheumatologist tomorrow but afraid it may be blood cancer. Am I crazy?

My wife has had sores on her arms and legs for about 1 year. They're not painful unless she picks at them. When she does pick at them, there's a small, hard, round ball that comes off. Attached is a photo. Any ideas what this could be?

Hello I have a question. For about 3 weeks now I ve had painful urination. The funny thing is that I get a burning sensation only after I urinate. I drink lots of water, no alcohol, not a single drop nor do I smoke. I m 21, yes I don t a drink or smoke, my primary care provider said it could be an STD that Is causing this. I was tested for chlamydia, syphilis, and gonorhea, all negative. Three urine cultures, everything normal. No genital warts. My prostate was also examined and everything is fine. I was given azythormycin, doxycycline, a shot of penicillin, and pyridium. Nothing helped. I saw a urologist and all I was a diagnosed with was dysuria. I m worried and I do not know what is causing this problem. Do yall have any idea?
