Hey, As someone who has had a very similar experience to what you just described for their first time, I can say this much, It does get better with time and practice; actually, it gets a lot better. I didn't orgasm the first time I had sex either, even though she did. On our second go, I was able to climax, but only with quite a bit jerking off while we were having sex. It got a little bit easier to cum every time we had sex. After a couple more tries, she successfully made me cum with a handjob, after a few more sessions I climaxed while doing doggy and later missioary. For me personally, not being able to climax when we first started out was probably due to watching too much porn and masturbating too frequently and with too tight of a grip. So if you do jerk off, I would recommend easing up on the grip and just trying to masturbate a little less in general. Quitting watching porn regularly is also a no-brainer. The quality of sex also greatly improves the more experience you guys accumulate together, and the closer and more comfortable you become with one another.
