I am aware that I have a large dick. It is 8.75 inches long and 6 inches girth when fully hard. When I am with a lady I think too much about her seeing me fully aroused. When we are kissing this is the only thing I can think about, and in turn, this renders me impotent because I get way too nervous. The only times that I can relax and get aroused are with girls who are inexperienced and/or exclusive to only me. Does anyone else feel similar?
