Wow! This was very educational to me. I'm also on venlafaxine, and have been off and on for more than 15 years. About 5 years ago I went on it more consistently, and at a higher dose.

I'm 38 years old. I... uh.... "concluded", based on my observations of myself that "I guess it's true, male sex drive must peak in the early 30s! Ah well, I had a good run, no regrets!"

Now I don't know what to think! Maybe it's the meds? Or age? Or both? Thanks for this! (meant in earnest, not sarcasm)
