Hi.
How you feel isn't "bad"; it is just how you feel. What is bad, though, is placing yourself in an uncomfortable situation. It's much better not to get physically close to anyone if you aren't ready for it mentally or emotionally, even if this makes you feel a little square.
Judging by what you said, you seem to have a done a pretty good job of figuring out what does and does not work for you. Recognizing the way you are feeling and not committing to anything you aren't ready for are both good ideas.
Though you shouldn't be in any rush to do anything at all, you might want to ask yourself why you are feeling so self-conscious. Overcoming self-consciousness is a life-long process and isn't always easy, but there are so many good reasons to become more comfortable with your body.
You might want to think about not getting involved in any romantic relationships for a while. It's really fine to just focus on what you want and what is appropriate for you in your life before you spend time focusing on someone else.
Or you might want to consider talking to the boys you date about the way you are feeling. Although this might be a bit awkward at first, putting your fears out there could help you to work through them or at least let you see them in a different light.
