I like shagging in front of mirrors, feels a lot better when I'm watching myself in action, my favourite is both of us standing facing the mirror whilst I'm shagging her from behind.
Reverse oral is good too, I like when I can see their fanny reflection in the mirror whilst going down on me.
I'm very vanilla so enjoy the main three:
Missionary when I want to see her face during and am feeling sensual
Doggy when I want to pump hard and fast (or she has a fantastic bum)
Cowgirl when I'm feeling lazy
I had my first mirror reflection experience during doggy only recently, it was slightly jarring and felt like an out of body experience for a few moments but also enjoyable at the same time. Oh well, I will have to keep visiting different girls until I can make my mind up, it's a tough job..
