What does a penis with the skin look like?

(F) im a virgin, the only kind of dick I can visualise in my head is one without the skin. People talk about foreskin over the head and the way it can roll and stuff I can’t even visualise that.

Yeah I could probably look it up in porn or something but I haven’t watched that in years and even then when I did it was brief, it’s just not really my thing even for curiosity sake. But If it’s really something you’d have to see to understand I’d see it, just want an idea of what it’s like and does in case I get with a guy who has it.
