It must be my damn bad luck that all 3 of the women I been in relationships with had much higher drives than me. I'm quite happy with it being twice per week as each time really feel drained of energy and prefer utilizing the time elsewhere.
Ex-wife : She wanted it to happen 3-5 times per week for as long as she was the one in control of the whole thing. The thing that absolutely got her off was knowing it was happening when I didn't really want to do it and it was particularly her joy when she could corner me into doing it when I actually needed work to be done. Thankfully with her she was always the one on top as that's how she liked it so it wasn't so draining and LOL usually I just let her do whatever she wanted to do so it could be done and over with.
Ex-gf : She wanted it 5-7 times per week, she had it in her that she liked sex to last 2-3 hours (inclusive of foreplay and post-sex routine) Finally she had enough of needing to pester and it was among the reasons we decided to part ways.
GF : One of the most common reasons she goes into a cold war is due to being told no to sex or more specifically to the type of sex she wants. She wants it everyday and sometimes more than once per day. Extremely infuriating as she doesn't like being told no to sex or even for it to be delayed. If she happens to have just returned from something that made her all sweaty and dirty but wanted sex she would go onto the bed and insist it happens, it drives me up the wall when she dirties the clean sheets, best part to it is she doesn't think it is a big deal.
