I've been with a wonderful girl for about a year now, and we're completely open and willing in the bedroom. Frustrations on both sides are starting to arise though.
I'm uncircumsized, and while phimosis isn't an issue, the foreskin retracts fine, the glans underneath is incredibly sensitive.
With past relationships, I always had a really hard time ejaculating during anything except intercourse. The skin gets pulled back during intercourse, and it increases the feeling immensely, yet if something touches it during fellatio or a handjob, it doesn't exactly hurt, but it is very uncomfortable.
When we first got together, I had little issues with reaching an orgasm from anything we did. Now it seems that I'll get right to the edge, and then I get a numb feeling and I get farther away.
Like I said, we're open, so she knows all of this, and she's expressed a desire for me to be able to ejaculate. I reach orgasm occasionally, everything except the ejaculate, and we're both getting a little frustrated over this.
