I wish I had a cock that big. But mine is even more pathetically tiny than yours is at just barely two inches long and no it's not due to being fat. I'm 5 foot 2 inches tall and I weight 89 lbs. I know it sounds like I'm describing a kid but I'm 32 years old. If you looked between my legs you might think I was a girl as my balls are also quite small. I also have humongous man boobs. So no shock that I have never been on a second date and precious few first ones. I lost my virginity to a prostitute a year ago and she couldn't help giggling the whole time. She also checked my I.D. three times because she thought I was a kid despite my pubic hair. At first she told me she doesn't do shemales but I explained to her I wasn't one and she then asked about my tits and I told her they just happened and that no I was not on female hormones. So she let me rub in on her pussy. Since technically the end of my "clit" did enter her between her pussy lips and I did ejaculate into a condom while just barely in there I am going to say that counts as losing my virginity. She insisted it does not and that all I did was rub her pussy with my "clit." She laughed and said I could have fucked her 6 month old niece and the baby wouldn't have woken up from her nap not noticing that anything had gotten between her legs.
A guy would have to be pretty pathetic to have a "cock" so tiny that it would be impossible to harm a baby with it.
Be grateful for what you have. I'm actually quite jealous of your much bigger cock.
