I've pretty recently gotten a girlfriend , things are going well and I'm happy. Now this is a first for me, so everything I've done (starting from holding hands and up...) has been a new experience.

Even more recently I got my first hand job, before she has kind of rubbed it through my pants, it felt good like "cool a chick is rubbing my dick" but it didn't feel good at all sexually. I don't think it was her fault, she tried a couple of speeds and grips and such, but I just wasn't getting anything out of it. She also stopped after only a few minutes, which I was relieved about since it was just feeling so awkward.

I think this might be stemming from the fact that I can't even get off using my hands. I usually use my mattress and a pillow. So its kind of impossible for her to make it pleasurable. I have always been like this, I think that my penis does not have a normal sensitivity. She was even rubbing the head of it, but i couldn't tell because it was dark until I actually looked down. Could circumcision possibly have something to do with this? I tried abstaining for a week, and then trying to use my hands - but nothing.

This really sucks so I'd appreciate any help.

Have sex.

Seriously. It's time for the upgrade, you can only fuck your furniture for so long kid.

Gotta be this, I see it making your cock less sensitive, it wouldnt happen to be callaced by any chance?

Fleshlight it for a bit.
Get back into the mood.

And stop whacking off into your pillow man.
I mean no...just no.

I heard circumsized people can't masterbate using convensional methods.

I'm circumcised and I can masturbate just fine

Lies.

Get her to give you a hand job with her vagina.

If the circumcision wasn't done properly this can have a major effect. Some people lose complete sensitivity and can't get it hard at all, other simply can't ejaculate. Simply going to have to work to find the sensitizity and take advantage. Tell her to use the hidden rub technic , she pushes it back inside you and rubs it around inside of you.
