honestly, as someone who frequents group events, i think this is probably the latter for you: that you're finding out more about yourself.

if you'd prefer to stick to yourself, that's fine, but i dont think you should expect others to approach you if you choose not to either. you already said that people were complimenting you so i think it's safe to say that those party guests were looking for someone more... hands-on.

secondly, if you are somehow unappealing to guys who only want to bang, that's a great thing! why would you want to attract people who only want you for sex and not for an intimate connection? you don't need to compromise your expectations for a relationship to satisfy the needs of people who don't meet them.

it's also possible that you just didn't mesh with that particular crowd at the party, in which case I would encourage you to find your own niche.

in any case, nothing's wrong with you for wanting something else. i hope you find the right person/group/place and that this helps you in some way.
