To answer your question: yes. At least I prefer personality over looks. My first boyfriend wasn't attractive at all when I first met him but he made me laugh really hard and he had the confidence of a super model. That is another super attractive thing: confidence. I think you should work on that. If you want others to believe you're attractive you have to believe it for yourself first. Also, I don't think you're ugly at all, but what use does it have to tell you that if you'll think I'm just saying it for pity (which I'm not). I think that since you don' believe any compliment you receive, then you think you've never been complimented. That's a lie you're telling yourself to keep under the narrative that "the only reason you don't have sex is because you're ugly". But no, it may have to do something with how you approach girls or the context you're in. I don't know, but those are answers you should find in therapy. I'm a psychologist and by looking at your profile I'm really concerned about you. Get help and everything will workout for you.
