I have been having trouble with busting too early since day one of me being sexually active. No joke, i normally last about 15-30secs (I am very lucky that my gf can cum riding me in about the same time). I did some research a month or two ago and saw that viagra can help with lasting longer because you get so hard that your penis goes slightly numb (less sensitive). I got hold of some and realised it worked.. slightly. I lasted about 2-3mins.
So I did some further research and found "dapoxetine".. so i ordered some. The first time i used it I took the pill about 1hr before intercourse. Me & my gf started intercourse and for the first minute or so it very slightly felt like i was going to bust... then it went away. 10mins in of intercourse i told my gf i cummed (but i didnt), i didnt want her to get suspicious haha. Right there that is a crazy difference and i didnt come.
Second time: A few days later, i popped the pill about 60-120mins before intercourse (can't remember). Once again, i very slightly felt like i was going to bust for the 1st min... then it went away. My gf was riding me for the first 5mins.. then i told her to go on her back (normally i last like 2 thrusts when i go on top). Anyway, 10-15mins later i was still thrusting away on top and felt like i could last forever. This time i lasted 20mins and didnt even cum. This shit is a charm.
I know this isnt a permanent fix.. but it is helping my confidence tremendously so hopefully i can work my way up so i dont need it at all. But no joke, i reckon pornstars take this shit before a film shoot.. haha i reckon i could even last 30+mins of pure thrusting.
