Would everything remain the same, except I would have a pair of breasts?
I'd actually be pretty unhappy. I can't imagine breasts looking good on me, or any other man, really. I'd feel misshapen, or I'd think I had some sort of fucked up cancer.
If I got to have a female figure and face with the boobs, then I'd be ecstatic. I'd have a skinny waist and no ass, but HUGE E-cups or bigger. I'd be like an anime character in terms of proportions. The breasts would have absolutely no sag.
I'd spend all day playing with my breasts. I've stated so before in other threads, but I absolutely fucking love breasts. I'd jiggle them, jump up and down with them, shimmy my shoulders, squeeze them, try to kiss/lick/suck the nipples, push them together, lift them up, move them around, and so on and so forth. I'd never leave the room.
Then, I'd go on webcam and be a HUGE tease to all the boys. I'm not interested in guys, and I wouldn't be doing it for them, but I'd just LOVE the power trip. Tons of people asking to move my hands out of the way so they could see my nipples and I'd say "NO SIR". I'd feel so incredibly powerful.
And then I'd find a really sexy lesbian or bisexual girl, and do my best to seduce her and get laid.
It'd be a good time.
