How can I make my first time having sex enjoyable?

Heck if the girl is willing to teach you everything, then sit back and enjoy the ride and of course learn everything she tells you or shows you for that matter. Just relax and go with the flow, be flexible and teachable and don't get your expectations up too high, just do what you can do and move on from there.

Make it enjoyable by just following her direction and making sure you do what you can to make each other feel good.

It will basically be enjoyable no matter what, although I remember when I first started having enjoyable sex it was with the girl on top. That way you don't get too worked up or nervous or anything, just let her guide it and ride it! Wear a rubber too so you don't have to worry about pulling out or any 'other' stuff. Hope this helps.

The only thing I can advise you is be a multi-tasker let you lips do something while your hands do something else while your body is moving while your legs are massaging hers its very simple advice but very helpful

I would say wait for the one that you want to do it with. I was really happy to wait to find the one that I loved. Don't rush into it. Make sure you get to know her. But remember the first time is always going to be just that. The first time. It really isn't that big of a deal.
