I'm 17 years old and I was fooling around with my girlfriend last night. We have been going out for around 4 monthes now and thought that we should move our realationship further. I have never done anything with a girl before and was worried that i would ejacultate early. But the problem was that i didn't. She spent the better part of an hour working on me, it felt great but i just could't reach the point of no return.

So my question is: Should i be worried or is this because i was nervous?
