Penis Size

So, I have a 4 inch hard-on. Ladies, how doomed am I in the sack?

At my college (yes, i feel the need to say college instead of school, because otherwise, everyone would assume that by school i mean high school, so...), we recently had a descussion about foreskins down in the commons area.  A lot of people, most being circumsized mind you, seemed to think foreskins are good ideas.  They acted like i was nuts for promoting circumsision.  They say that masterbation and sex are each more pleasurable WITH a foreskin.  I guess, to me, I have never known anything but a circumsized penis, plus I'm still a virgin, so little thought have I needed  give the subject, as of yet.  It just seems icky to have a layer of skin over the penis!  Isn't it weird?  I guess for an uncircumsized person it would be the same situation I have.  Not knowing about other penises.  Oh well. So far, I'm happy how I am. Oh yeah, also, my dick is about 6 in.  I don't even know if that is small or big or normal or what.
