So I have been waiting for a long time and finally lost my v-card to a girl I really like. We messed around for a month or so beforehand but only now have started having sex. We've been having sex for a week now and she accused me of lying about never having sex before so I am assuming I am doing something right. Anyhow we've stuck to standard missionary position until now but have a ton of foreplay so its always pretty exciting. Well my question is this: what's a good second position to try (simple, easy to do, enjoyable) and how soon is too soon to try something new? I am happy for now but I want to make sure it doesn't get boring or anything.
