I'm usually very dominant with the girls I've been with, and it's generally how I like it. Sometimes I get overwhelmed with a desire to be submissive for a change though. My gf is an ex-christian. I'm the fifth guy she's fucked since she lost her virginity two years ago when she was 22 but she let me take her anal virginity, which she enjoys. She's joked about wanting to fuck my ass with a strap on.
I've told her no way, but secretly the idea turns me on. Lately on the nights she doesn't stay over I jerk off to thoughts of other guys fucking her and even sharing a huge cock with her. Sometimes the thought of both her and me being on our knees worshiping some studs huge cock together turns me on, or the though of letting her watch me get my ass fucked by a stud. But when the horniness passes these thoughts sound disgusting to me, so I'm pretty sure if I ever did do this irl I'd regret it. Though I could probably deal with sharing her
