Hi there ~ I understand your concern. You may be having a fungal infection or any other kind of infection which is affecting your sexual health. You may also have a side effect to any local antibiotics or you may have poor sexual health, please consult your doctor to find out what the reason for the itching is. Over the counter anti itch agents might be helpful as well. I am not sure what you are thinking. However, firstly you might need to consult an psychiatrist to find out if you have any difficulties in your libido or have other mental health concerns like depression. Otherwise, you have a very common problem of erectile dysfunction and / or premature ejaculation and it can be easily treated with medications available during this time. The class of medication is called phosphodiesterase 5 inhibitors (PDE5Inh) selective serotonin reuptake inhibitors and it also helps with decreased libido which is a result of depression if you are going through one. I advise you to consult with a qualified psychiatrist who might be able to help in this regard. I hope this helps. Take care and have a lovely day!
