So me and my SO have mastered shower sex, and we've tried doing it in the bath and found it really hard, we ended up doing doggy in it! there's a pretty big height difference (he's 6'4 and I'm 4'11) so if we can master shower sex I think anythings possible! Any tips/positions that would be any better than doggy? Any type of lube that would work better?? Help?!
