Douching

Okay, so I'm on birth control and I take it as I should so my boyfriend and I decided it was okay for him to cum inside me. We have sex pretty offten, more than 2 times a week and he usually blows his load in me. Since it's not healthy for my down under parts to douche as often as we have sex I was wondering if you guys had any suggestions for alternative healthy ways of getting clean down there after he cums inside.
