Can Heat Cause Reduction In Ball Size, Disinterest In Sex? Testicle Scan And Hormone Test Revealed High Prolactin

Question : Almost a year ago now I slept with a girl who wanted to sleep with her leg up in my balls.. One night I let her do it, and immediately after I noticed a drop in my libido. I could hardly get an erection, I didn't have any morning wood for about a month, and for about 2 weeks my semen was watery and clear. I know that heat is bad for testicles (her leg felt pretty hot) which is why I didn't let her do it at first, but anyway, it seemed like a completely normal thing for her. My balls also seemed a lot smaller than before for a long time, though they seem to be returning more to normal now. So although I now have more or less normal semen (it still seems clearer than before) and morning movements, my libido is nothing like what it was before, and I can't really get interested in sex. It's been like walking around with a dead animal between my legs for the past year, my balls just feel numb as if they aren't even there, and I feel impotent and uninterested in and disconnected from life. I went to the doctor and they did a testicle scan and a hormone test, and both came back normal, except I have high prolactin which they said was due to stress. Now they're sending me to a psychaitrist. I'm aware that a lot/most of sexual arousal is in the mind, but the lack of sensation and libido seem so phyisical to me. I look at women in the street and try to remember what it was like to feel attracted to them. I also seem to have very little energy these days... What can I do?
