During intercourse I last hardly less than 30 seconds. As long as I enter inside my partner, I release myself.
However, during the second attempt I usually go up to 5 to 20 minutes. I'm now confused. When I see online video lectures (on youtube) or related stuff on the online websites, some says it is a sign of PE. Whereas, some says it's common. And, as long as my second attempt is successful I should not worry about it. I'd appreciate any expert's suggestions.
Also, it's been now more than 7 months since I'm in a relationship. I'd say, in a week we have sex at least twice (usually) but my partner is not getting pregnant. I'm a healthy guy with a good and strong physique (I do weights and martial arts). But still, I don't see any success in this process.
I'd also like to mention here that I have never had sex in the past, so, according to some available information over the internet, it may also happens due to excitement. PLEASE, YOUR SUGGESTIONS WOULD BE APPRECIATED. THANKS.
