and now i am going with the not-popular theory, dude, he makes you happy and you are(i assume from the way you speak and the age /i/ was when i took that class) under twenty, at this point it could just be you are just spending a lot of time with an honestly /good/ person of the sort you want to be with and they are /there/ culturally speaking you have been conditioned to respond favorably to a companion like this dude and as a young person the libido is close to follow

or you could honestly like dudes too, i say see if you get a similar or same response from other males, if you don't ping it might be just this dude or even just the idealization of this dude
