<human>: Okay, so I'm a late bloomer. I didn't get much male attention in my teens because I was hideous, ugly and didn't know a thing about make up or fashion.

I'm now 20 and feel a little bit more secure about myself. I use some discrete make up, I tend to dress up or dress in clothes I feel feminine and beautiful in.

One thing that bugs me is that I have always been insecure when it comes to approaching the opposite sex/or girls (I like both lol). I never approached any guys when I was younger because I believed no one could ever like me or be attracted to me because I was so ugly. 

I'm using Tinder because I don't go out much so I don't have a lot of opportunities to meet new people and so far I've been talking to a very attractive guy who is also very nice and funny. We are meeting up for the first time soon and I'm so nervous about it. I'm afraid he will get another impression of me and not like me, not find me attractive etc.

So basically...how do I approach guys/gals i'm interested in without making a fool of myself?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Late bloomer, don't know how to approach people I'm interested in. A bit of bad self esteem and confidence issues.
