Suck it up, buttercup.
Since when did school come with a clause that you don't have to do the bits you don't like? Not everything is enjoyable kid, but kicking up a fuss and being stubborn about it isn't gonna make people respect you for standing up for yourself, it just makes you look like a mong. Sexuality has nothing to do with it, even if you're camper than a row of tents (my femininity is somewhat infamous and I love football), and the sooner you accept that you sometimes have to do things you don't like the sooner you'll have acceptance - and hell, you might even enjoy yourself
