Where Oh Where To Cum

This is for guys and / or girls, but during sex how do you determine where the guy is going to finish? I know that there are different scenarios and situations where this may not apply, but in your "normal" day to day sex, is there some sort of dialogue that occurs before during or right before you cum?

Just curious of this dynamic for other couples. I guess if you use condoms there isn't much to discuss, but if not, I'd like to know how this goes down.

For us, I'll usually let her know when I'm getting close and thenI'll ask where she wants it or she'll ask where I want to shoot it. I'll usually request her face and she'll say no and then there is some sort of negotiation as to whether it's in her mouth, on her tits, inside her or on me.

If not in her, I think the position determines...who's on bottom usually gets it on them.

Sometimes the discussions are a bit comical!
