Thats simple. Not going to elaborate deeply as you should see my point clearly in few words. Again weither i believe this or not this is how it is. Don't judge my beliefs here because we're not speaking about my belif just about the issue at hand and what I think about the situaion in whole.
Female thinks of consequences of sleeping with teacher; "hrmm everyone is gonna call me a ****, guys aren't going to want to date me, I hope no one finds out, I will be LABELED."
BAD DECISION
Male thinks of consequences of sleeping with teacher; "Boy Steve is gonna be salty as shit when he finds out i slept with ms. (insert name here)!, Can't wait till everyone finds out I'll be like the don in this school".
NOT SUCH A BAD DECISION
Two of the same actions with two different genders makes the decision different.
Would I feel the same way if my 16 year old male slept with his 30 year old male teacher?
That wouldn't be any different. If my son was gay I would already have to worry about him not being socially accepted and that would bother me. I have nothing against gay people but alot of people do and naturally if I could choose I would choose not to have a gay son just because his quality of life COULD be damaged. Notice I said could. Would love him the same if my son was gay or not though.
