My girl friend was much the same way, loved our weekend get aways. She knew how many women I had been with and said she wanted to catch up with me. After a short slut phrase, she decided to look for quality not quantity.
You know I can't put my finger on it but there's something about giving a guy control over me. Telling me what to do. To me it's so kinky and erotic. It really turns me on. I usually like to take control but sometimes it's fun to just let someone else dominate you.
My sph fetish is definitely the main driver but I think it is also enhanced by the fact that I am outwardly much more alphaesque than beta personalitywise and general demeanour. I am confident, not socially shy or awkward around men or women and have a rather robust physicality and fearlessness without being overaggressive or confrontational. This tends to hide the fact that I am in fact that I am very beta when it comes to sexual activity. It is an extra turn on for me if far more beta guys outman me. I may not show it in public but if another guy sees that he has a way bigger penis than me and of course sees just how tiny my cock is it secretly arouses me. This is especially true if a woman sees how poorly I compare. I had an experience where a rival for a girl's attention was pretty much conceding he had little chance getting her attention and was very shy and trepidatious around her. I had been flirting with her a lot more and he seemed to be resigned to taking a back seat. That changed however when we crossd paths in the changerooms at a leisure centre ( not the first or last time that has been the arena where my tiny penis was outed by someone I knew) He looked quite chuffed when he saw how tiny my dick was especially compared to him. He was totally emboldened and far more confident in his pursuit of the girl in question. Neither of us won out but I was secretly aroused by the whole thing. The relatively beta guy suddenly becoming the alpha and me falling to beta status because of my tiny penis.
I like being poked fun at a little in a teasing way over a few things: the size of my penis when soft, the fact that I have wetting accidents/wear pull-ups and diapers, and cumming too quickly. The reason I like it is because I don't feel humiliated and there's a rush of confidence I get by refusing to let those things get to me.
The humiliation aspect is a bit of a misnomer because the thrill of the potential embarrassment/humiliation in regards to my tiny size supercedes the negative aspect. I often fantasize about my penis being even tinier I have even purposely had a cold shower before having sex with a paticular girl one time just for the extra kick of her reaction when she would see it no bigger than a baby. I have relatively small balls as well and they shrivel up to child size as well.
