Not sure if this has been addressed before or not.

I get concerned that after the first splooge, there will be traces of jizz on my weiner, which i obviously dont want to get in or around her vagina. I usually end up running my dick under water in the shower, but this is a bit awkward. And it takes away from the "moment" when you guys just wanna bang away.

Does anybody have tips/ a system worked out for this?
