Why can't I get a boyfriend

I know this is kinda long but please bear with me!

so lately things have been annoying. not everything but this one things in particular like. I have this friend, we had been friends for awhile she and her sister are absolutely gorgeous they're both tall and really skinny, vs me who is tall but I'm bigger compared to them ( I'm not chubby or fat) I just have more curves compared to them. but lately we have been hanging around a lot and they are always saying how beautiful I am and how I should get a boyfriend. but what the hell people have always said I was pretty and what not but the real question why can't I get a boyfriend, I'm not mean, I'm actually quite nice. I don't give off a bad vibe but what gives is the area I'm in? or just boys being well boys? please help me understand!
