His and Her Health

Yes, but these changes happened when I was only 19? My testosterone levels are within the normal range (checked last year).

Looking for any input about this issue...

I had an *extremely* high sex drive when I was young, until I was 19. I was very easily aroused and had multiple orgasms. I loved sex. But nearly overnight the sex drive and arousal stopped. However, I could still have orgasms, though not multiples. Even after orgasm, I haven't experienced any lubrication in 20 years (I'm 39 now). I just don't get that "horny" feeling. Just wondering if anyone has any ideas as to how this can happen and what I may be able to do about it?
