I don't think my man really cares what I look like during sex. As long as he's getting it, he's a happy camper.
But...we do like to role play...kind of lol. He pretty much knows what's in my sexy drawer, so he'll suggest I wear something. And I pretty much create a whole new persona to go w/ it, including makeup, hair, shoes, and accessories. I think it's fun and it gives me a chance to practice makeup looks I wouldnt' normally wear AND I have an excuse to buy more shoes lol. He likes b/c ....well he's a man. Sex usually comes at the end, but I'm sure he's not paying any attention to my makeup by that point.
Although, there has been a time or two afterwards when he told me how much he really like my makeup. I couldn't really tell though if I banged my face out or just banged him out, lol.
