Your young, hormones all over the place, its normal to have some confusing bi-curious thoughts.
Doesn't mean your gay, doesn't mean your bi-sexual, just means your brain is in a fumbled mess at the moment and trying to see if you want to pursue an experiment.
Lots of straight guys go through this, most deny it as it passes pretty quickly but it varies from person to person.
Some fantasies are great in the brain but a bad idea when it comes to the crunch as it may not live up to expectation or you may get a very unexpected result from it.
Go with the flow and see where it goes because it may just be a passing fantasy, you have nothing to worry about, experimenting with a guy is also quite normal if it comes to that, doesn't mean your wife and kids are out the window further down the line.
There is nothing wrong with thinking a guy is hot, as long as you don't get turned on when you see them. If you think that a guy is hot, it just means that you have a good self-esteem and you aren't insecure. Sometimes I see a girl and think that she's hot, but I don't want to have sex with her or anything. Just secure in my sexuality and myself.
I don't know bro. Sometimes when I see styles or bodies that girls like I'll see if I can apply some of those traits to myself. Just things like clothes, hair... even muscles... at least in the sense that I'm like... I should work on that more... but nothing sexual.
nah not bisexual, I know for a fact that I even me, have those thoughts as well, I frickin hate it it does creep me out, but come on every guy has had sexual fantasies or thoughts about another guy, it's completely normal.
