When my boyfriend goes down on me, there are times where I have excessive urination. It's really embarrassing. I know it is not ejaculation.. it is urine.. and there are times where I have completely soaked mine or his bed.
It only happens during oral sex, not when I masturbate and I don't know what the problem is. Please help if you can.. it's really effecting our sex life.. it has come to the point where I don't want him to go down on me at all, and that's the only way I orgasm, which is a different problem all together.

Does he have a problem with it?

Have you tried emptying your bladder before you have oral sex?

Perhaps it's the contact of his tongue with your urethral opening that stimulates the reflex to urinate...

See if avoiding the urethral opening helps.

My first thought was go before you have sex as well. You said this isn't a problem during masturbation, how similar are the orgasms? Secondly, do you stimulate the urethra when you go normally?

There is a lot of stimulation of the urethra... but I don't like direct contact..

I meant when you urinate do you stimulate the opening to "start."

I second the advice to go pee right before you have sex. What isn't there can't come out. And no... that really isn't all that uncommon given the level of stimulation oral sex can provide done the right way.
