Why do i like chubby guys and really hot girls?

i'm 14 year old kid (5"8', 170 lbs.) and for some reason i'm attracted to chubby guys (my chubby friends, other chubby guys in my school, etc.) sometimes i think about them in other ways if you know what i mean. but, for some reason i have this really hot girlfriend and i actually have a way with the ladies. i mean i want to grow up straight, but sometimes i think about what if i kinda experiment with other chubby guys. but then i think about the rest of my life. see, i'm really good in baseball i'm on varsity right now and i have a lot going for me and i dont want to mess that up. can i still be in love with a woman and have sex, kids, and a family with her? but still experiment with chubby guys probably before like in college in stuff? but honestly i dont want to really do anything in person with a chubby guy, but i like to think about it. is everything okay?
