Yes, v nice pics man.
A fellow nerd speaks here - don't ever think being an 18-year-old virgin is unusual or undesirable. Take plenty of time to consider when and with whom you will lose your virginity... It's something you can never get back.
(And if you need to get off, you have the web, which is something I just barely had when I was an 18-year-old virgin!)
Be proud of yourself and your body and take care man.
