Re: Help a guy out =P
I'm a guy, but I gotta answer this! I think most sensible girls SHOULD say that the penis isn't nearly as important as the guy it's attached to. I know this is hard to believe, but most girls aren't as penis obsessed as many/most guys are. They actually care more about the guy himself.
If you're self conscious about anything (in your case foreskin), it's always a good idea to discuss it with her, before you expose that part of yourself. I think you'll find they're more understanding (even if they have little or less experience with foreskin) than you might initially think.
