I am in relationship with a girl for over 4 years now. We are high school sweethearts and first sex we had with each other (both were virgins before relationship). We have normal sex frequently and as far I know we are faithful to each other. Yesterday on some picnic, she made a comment in front of her female friends that I didn't like. I was holding some quite big sausage in my hand and she said - how it is like for a change to hold a real size in your hand? I was absolutely stoned. First of all, I felt embarressed because those girls are also my good friends and second - no one likes to be said in public that he has small penis. After this comment I was quite pissed off and started to rewind my memory in a past. I figured out that she made similar comments at least 5-6 times in the past. Sometimes in public comparing my penis with small things and sometimes when we were alone. But it never been this harsh/strong. My penis size in full erection is 17,5 - 18 cm. Not very thick (not sure about girth) but I never had problem to satisfy her. I think that this is not small size. Medium/average yes, but small for a girl that only had sex with just one guy (me)... I don't think so. I asked her why she said that and her answer was that she was just joking, nothing serious. I don't think so... Why she keeps making that kind of "jokes"? It is quite offending and embarrassing. What do you guys and girls think? I don't really have an idea.
