19m “straight” but constantly horny and can’t stop thinking about cock

I’ve been consistently working out/lifting due to wanting to look better and possibly wear more flamboyant/fem clothes that require a more hourglass figure. However I’ve noticed that ever since I started hitting the gym consistently I’m always extremely horny and it gets me started on thinking about cock. I’m a virgin and don’t really have an outlet for these feelings and it’s driving me insane.
Has anyone else experienced this?
