TIFU by jacking off too much

Well, until today, anyway. I (19M) finally explored my girlfriend's (18F) body and lost my virginity. I was happy doing it with her, but then while we were doing it, I realized something: I couldnt feel anything. And my donger was starting to become soft even tho the woman of my dreams was literally on top of me riding it. She was feeling good and she said i was doing great, but soon enough she was already getting tired and she asked me why i havent came yet. Not wanting to make her think she wasnt satisfying me, i blamed the rubber, and started eating her out to distract her. It took me 4 hours and 3 condoms to finally shoot my load, and it was the best one i had in all my life. Still, i wished i could've came more and really enjoyed my first time with her, and i wished i didnt choke my donger as much as I did before today and desensitized my dick so much, so that i could've felt things better. On the bright side, i learned a lot of things about a woman's body (one of the things i learned is that the clit isnt as hard to find as people make it out to be), my girl was happy (i was so relieved when she said that i wasnt as small as i thought i was, which definitely boosted my confidence), and lastly, my friends cannot tease the shit out of me for being a virgin anymore, because im no longer one, so to my virgin brethren out there, dont jack off too much, or you wont enjoy your first time.

TL;DR i jacked off too much before i lost my virginity, and i couldn't enjoy my first time as much as i wanted to. Atleast my girl was happy, i guess

Edit: Thanks for all the advice, guys. I've read a lot of comments and yeah i feel like nerves were also a big part of why i took so long, probably because i was scared of not being able to satisfy her. to answer some of the questions, yes, we did take breaks within those four hours. i boned her for like 3 times only, and most of the time was either us touching each other or eating lunch. and yes, we did try a whole lot of other positions, not just her on top. there was the small problem of our height difference though, but we managed to work around it with pillows. and lastly, yeah my condom was probably too tight. Thanks for y'all's advices and i'll make sure to lay off the jacking off so our next time will be better. Cheers!
