So my fiance and I have been having shower sex when I'm on my time of the month. The problems we've been having are: We can't find reasonable positions, he isn't able to enter me all the way due to lack of lubrication and he finds that he isn't able to cum while standing. We're looking for some tips on positions and ways to help us achieve the best experience for him and I while at the same time not wanting to pass out from tedious positions. Thanks!!
