If someone is going to like you because you have a crap load of make up on is not someone you want to be in a relationship with. Would you rather be with someone because they like you for your looks or because they like you as a person? They should be looking for the beauty in YOU, not for beauty in general.
I can't get a boyfriend with or without make-up on, so make-up isn't going to be the guarantee to finding someone. I have seen your posts on here and you do appear to be overly sensitive to people's comments, that may have some part in the situation. I don't mean that to sound nasty, but I think it would help you a lot to learn over time not to take things the wrong way, i.e. if someone says that you can put make up on if you want but you as a person is more important, they are not telling you that if you make yourself look like a slut you'll get a boyfriend. They are saying that fake beauty may find you someone, but you'll only find a genuine guy if you are are beautiful on the inside.
Building your confidence will help you a lot in finding what you are looking for. If you feel you may be more confident wearing make up, then try it, I NEVER used to wear make-up, now I wear it all the time. I even put make-up on just because I'm sitting at home bored. I am not telling you that if you put make up on it will solve everything, but it might boost your confidence a bit.
Do you try talking to any guys? Have you ever attempted to get to know someone you like?
