So I am at university and I go to my friends place for parties, his flatmates, 3 girls seem to think I'm gay.

I don't have a high pitched voice and I don't wear flamboyant clothing, but I usually do dress well and put a lot of effort into my hair. However my friend told me that these girls think I'm gay because I'm ''too sharp'' and ''chilled back'' (I've been told I come across as very laid back).

They also said I don't have a manly voice (even though I've been told by most my voice is deeper than normal).

He even told these girls that I've scored with other girls but they didn't believe it.

This is a terrible first impression and I likely won't be able to overcome it. What the fuck do I do?
