I think the issue is that he is not communicating with maturity (e.g. talking to her afterwards in a chilled out way) or compromising (letting her ride him her way, then doing it his way) or explaining what's the issue. Instead he gets "mad" at her and physically stops her from also engaging in sexual positions that work for her pleasure or even checking what works for her in the first place. That is immature, selfish lovemaking and potentially controlling. Just sayin'!

Kitten - soooooo glad to hear you're out of that situation, you've made my night
