Is the bladder supposed to feel weird during the act?

So, with such a long time since my last tryst, I had conveniently forgotten how much my bladder can't stand PIV sex. Now that I'm starting up a regular thing with a friend (long story on this, I won't bore you with it), I am concerned about this topic and want to know if other women have it and what can be done for it.

Everything fits fine. Lubing up is fine. Actions are fine. After about a minute of thrusting, my bladder starts feeling full and does that "painfully have to go" feeling, even though nothing is in it. This has happened before with Mulder and the couple of other friends. I generally let them have their fun and tell them not to worry about me ... I'm just wanting the damn thing to get over with already ... Needless to say, I know there's more to sex than PIV and rather enjoy the rest of the act.

Does the pain/full-bladder thing ever go away? Is it even normal? Psychosomatic? less

So did yours just develop out of the blue or has it always been that way? Mine has always been this way, which might be a reason why I stayed in a celibate marriage for ten years - not having to deal with this bladder issue.

My GYN and all say I'm perfectly normal and arranged perfectly fine down there, so there's nothing wrong with me physically. less
