Detailed Answer:
Hi XXXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Following are the chances of STDs for each infection from a single Unprotected vaginal sexual intercourse between a male and female.

Genital Herpes 30%
Gonorrhea 25%
Chlamydia 20%
Syphilis 20%
Chancroid 15%
Genital Warts 10%
Hepatitis B 5%
HIV 0.9%

2. If you know that she is not having any disease even then she might be having a STD which both of you are unaware of.

3. Always have sex with condom if you are having casual sex with multiple partners.

Hope your query is answered.
Please write back if you have any doubts.
