Hi. I know this might sound completely opposite for most people usually post, ie premature ejaculation. My problem is that it normally takes me a minimum of 10 minutes masturbation to get off, and sometimes even an hour. It takes at least 30 minutes to get off during oral sex, and usually takes about 20-40 minutes during regular sex. Part of the problem was that sex felt duller the older I got (comparing 21 years old to 15 years old). I fixed this using omega-3's, choline, and detox herbs to improve the feeling. While the sensation got much better, it did not effect the duration at all.
This is a problem because sex is too much of a strain for me or my parter (especially during oral), and it makes it only possible to do it once a day without phyisical irritation. Any open ideas/ solutions welcome
