Hi Be
Just joined he forum. All my life I have your situation. Talking recently online with a lot of guys, I found the full spectrum of totally straight to totally gay, including married guys who remain curious and like discussing intimate details. Others like guys, even looking at them but without ever wanting to touch . One guy described himself and a bunch of rural lads as teens being very open, showing and discussing and comparing each other. The curiosity he put down to male bonding, confirming male identity. to me it didnt sound gay.
Sounds like you have a great connection with your dad and mum , do try to get out, meet people or go to places where u can discover yourself safely, or open to brothers cousins or friends. Swim and gym maybe to get body confidence and easiness with other guys perhaps.
Best wishes,
