Hey Ladies - From Indiana!

Ok, so I am very new to this whole thing.  I have been reading a lot of "coming out" stories -- trying to learn and hoping to get some answers for all of these questions, thoughts and feelings that I have.  I would like to introduce myself (and hope that the Judge Judy moderator doesn't yell at me for putting this in the wrong forum)!

I will give you the (newly bankrupt) Reader's Digest version--

So pretty much all of my life I have had mad crushes on girls (ever since 1st grade).  I tried to dismiss and supress these feelings, but to no sucess -- I still think about the lady-folk all the time.  I have only dated and have been physical with men so I really don't know how I would relate to a girl physically.  I really, REALLY want to find out, but I live in a small town in Indiana and when I do go out to gay bars (with my gay, male friend), some girls flirt with me, but that's it.  I don't approach girls at the bars because they are with other girls and I don't know the rules about that -- is it the same when a girl is with a guy -- forbidden territory?  I usually tell them I'm straight anyway and they say, "That's what I thought, you look straight."  I know I missed some opportunities, but I guess I just chickened out.  Well, I'm tired of chickening out!  

Can someone help?  I am all mixed up right now!

Thanks!
