Early evening, most of the time. I like to go to bed clean, and then be clean in the morning without having to get in the bath tub or shower first thing in the morning. That way I'm ready for evening or morning sex.
My Man takes a Jacuzzi bath and then a shower every morning, and sometimes gets into the tub with me in the evening. He even takes a shower before dinner if we are going out. He's a very clean man! Sometimes I get into the tub with him when he gets in in the morning, but that's usually about 4:00 or so AM and lately I've been so fatigued that nothing will get me out of bed (save a sick child or a fire) that early.
