I am about 5 1/2". But I could hit the G spot on my wife. Still I wanted her to try larger cocks. We got married right out of high school and were both interested in a little kink so we started doing other couples and threesomes. I think everyone was larger than me. Most were 6 or 7 inches. She does like the larger sizes mainly for their length. But out of all the guys that have fucked her very few ever hit her G spot. One guy and one woman hit her G spot while eating her pussy. She really liked that. I felt very submissive and became a cocksucker...and a sissy. My wife loved the kinkiness and there's not much we haven't done.
