I think you’re pretty much between a 2 and 3 on the Kinsey Scale… If not certainly a 3. You’re attracted to girls, you like making out with girls, etc. It just so happens that you haven’t found the right girl yet. That will happen eventually.
As for tips, check out the sex advice tags page.
But the easiest thing to stress is to trust your instincts. Think about what YOU like and then transfer it to her. You change and adapt according to the response she gives. Trust me, you’re not sexually inexperienced, you know what works to make yourself orgasm, now the tables are turned and you have to apply that knowledge to another girl. Maybe she’ll even teach you a thing or two… 😉
