You enjoy subservience because of your sph fetish. This is exactly what my wife taught me long before we were married when we were just high schoolers. She educated me as to what a normal size penis was by comparing me to this guy she was fucking. We were friends and she let me try to fuck her just to show me that I was woefully inadequate and too small to really penetrate her effectively. I was totally humiliated and she couldn't stop laughing but ended up apologizing. Then she told me a hard truth that no girl would ever accept me for very long.She was right. As soon as a relationship would reach the point where me and a girlfriend had our first sex attempt,I would fail miserably and the girl would end the relationship. Some would be kind about it and just move on quietly. Others would have a field day and humiliate and blab to all her gfs. A lot of them didn't believe the rumors of how small I was and would go on mock dates with me just to see for themselves. Back to Shannon,my future wife, told told me I needed to get used to it and said I was ment to be a subbie. I didn't know what that ment so she explained.She told me I was best suited to assist a girl after she had sex. What she ment was I should offer to clean up a girl instead of trying to fuck her.I was told that I'm not considered a good choice for a lover and should accept my place as a clean up boy. Oddly this started to appeal to me. It was the only way I could relate to girls and they seemed to appreciate it so I became the pussy cleaner for a small group of Shannons friends.This soon turned into a fetish for me.
