So I've been with my girlfriend a while and we've been having sex no problem...until a few weeks ago she slept round and we had sex 3 times in a row, by the 4th my guy was tired out and i couldn't keep it up. Since then every time we've tried to have sex I've *** within a minute. I don't know whats happened cos i have lasted over an hour before and had no problems up until then. Its like I've just suddenly lost my mojo and as soon as we start I'm ready to go, Anyone else had this or know anything to get me back to my former self as its embarrassing and awkward.
What should I do?
