I haven't heard of a disorder like this, but I'm not a sex expert either.

I just wanted to respond to your Q's: Chances are most likely that he is not real experienced sexually. My bf, for instance, frequently will relieve himself in the shower before a planned outing is to occur. Otherwise, he states that there's no way he'll make it.

When men are young and inexperienced, this type of thing is VERY common. I guess that they haven't learned control yet??

Hopefully, a guy or two will come on this thread and share their personal experience or opinion on what's happening.

Best wishes to you!
