LMAO @gondar1 - @Vitko - if you are lasting 15 minutes, does the woman want you to last longer or do you? I would ask her - 15 minutes of intercourse if more than enough if you spend lots of time with other types of sexual contact so she is able to orgasm too.Life is to short, I got shit to do. If I can't blow, take a piss and get my jeans back up before the commercial break is over then this broad is getting traded in for one who knows how to do her job properly.
It is possible to go over 30 minutes or 60 minutes, but most women I know, do not want to have sex 30-60 minutes. There are exceptions and if she is really into you then she may be a woman who has multiple orgasms.
The SSRI comment is a real side effect but I would never mess with selective serotonin re-uptake inhibitors to make orgasms and pleasure difficult. Training kegal exercises - like you do when you have sciatica, can help you hold off for 5 minutes or longer if you do them daily but look out when the fire hose gets turned on lol.
You can buy numbing gel which wears off at any store that sells sexual accessories. She may feel some numbness as well, but not as much as you.
I would stick the natural method indicated by @Monk on Tren.
You could find in a year, you have trained yourself subconsciously to turn off the pleasure triggers to last longer and find it hard to get off period.
Not a problem you want.
Even though it kills my desire too, Deca causes delayed orgasm and is annoying as hell and my prolactin is fine. Nothing I can do about it hence I would not add in more PED's to change your time to orgasm or you could just end up with other issues.
This question comes up all the time and I always say ask her if she wants sex longer / ask her what she wants period. I am very open with women so I know what they want.
