I masturbated for 2 and a half hours straight and not sure what happened.

So I have been abstaining for about 2-3 weeks, and recently my body was feeling mega horny and wasn't even too focused on the sexual pleasure but just wanted to release.

I look at the clock an it was about 12:53 AM when I started and close to 2:30 AM when I finally came. I wasn't using my hands and instead just rubbing my penis up against my blankets desperately trying to make it release.

I like abstaining more than masturbating, but I just didn't know if this was normal to have it rubbed for 2 and a half hours just to achieve a small orgasm.

Also for added context, for almost the whole time I felt I was getting close and feeling really tense. Almsot like it was ready to come out but just never got to that point until 2 hours later.

Any thoughts?
