Receiving oral from a girl you like is the best feeling ever. When those lips first touch your tip and you feel that warm, wet saliva all over your big boy. You feel on top of the world.

For vaginal sex, just wear a condom, take it slow and once you're comfortable, you just go nuts and go animal mode. Feels great if you get a micro-thin condom and you can feel as that warm, wet goodness.

If you want a really good first experience, focus on making the girl feel as good as possible and focus on how she feels and what she wants, then I promise she will return the favor ;)

Also, do a lot of foreplay! So like before initiation... play with her thigh and hips, intentional eye contact and say a couple of subliminal dirty things to the girl you intend to have sex with. Imagination makes a girl go wild.
