I feel uncomfortable about my dirty thoughts.

Well, in your age, your body is overflowing with hormones, so it's pretty natural to think like "that" of many.many things. Such sexual thoughts should not be considered as "dirty", it's completely natural and healthy to have thoughts like that. I understand that آپ find weird to think of that بھیڑیا "that" way, but I think you'll grow it out soon enough.

All I would do is think about a celebrity crush یا something.

I would refer آپ to my friend Shadow354. He'd be able to answer your سوال better than I. As a 15 yr old wolf, he's best suited.
