Problem with swimming

Hello all of you, this is my first post here and I wanted some help. The problem is that I can't properly swim the front crawl. I can just a little bit, but I get tired too quickly, I move really slow and I don't know how to properly breathe during front crawl. But I can swim the back crawl good enough in my opinion and I prefer the back crawl to front crawl much more. But it seems to me that only women swim the back crawl (I'm a 16-year old boy). And is it a shame that I can only swim the back crawl and not front crawl. And because I can't swim the front crawl, I don't want to go to the beach in summer to swim and don't want to go to the swimming pools in winter. My mother always kinda bullies me if I say that I don't want to go to the beach or swimming pools by saying that I can't swim.
