recently changed girlfriend and started having sex with her 4 weeks ago.
First week of sex was fine.
second week started feeling a slight burn on testicles but didn't pay much attention and noticed i started to loose erections.
Third week of sex i just could not keep an erection .
Was prescribed doxycycline day 3 now still no improvement .
The symptoms are as follows :
Burning ,aching sensation on balls
burning sensation on penis, although pass urine fine.
Very hard to get an erection ,can't hold an erection.
Today had a chat with her about it and she said about 10months ago she had a yeast infection which went on it's own and didn't see a doctor .
What's the reason for this ?
