first of all apology if i am posting this in the wrong location - i did search for matching posts but couldn't find any.

...now, my gf and i have been sex for a few months and i find that i can only get myself to feel something is when she is on all fours and i build up some speed. beyond that i tend to get very little amount of feeling regardless of if she's on top or I.

i am circumcised and and do masturbate regularly though even that i find that i not sensitive enough. This does mean that i have to work hard thus wearing me, which a few times has meant losing my erection during sex (not good for the male ego).

...so my question is am i doing something wrong, is it something i need to get checked or other...?
