Many of you may know increasing serotonin by means of ssri's can delay sensitivity and help control orgasm. Sometimes these medications may drop your sensitivity and libido too low that you can't perform. I just wanted to share my quick fix solution. If I take 300mg of 5-htp at one time I get easy erections and sensitivity goes down so that I could last for awhile and orgasm is controllable. This may not work for everyone and a few of you may already know this.. but just thought I'd share.
