 i hope i can achive my  porpuse of growing female breasts. But i want staying male, only that.

Good luck with that.

EDIT: Sorry bitchy Drew there again.

Be prepared that estrogen will do more to your mind and body than just grow boobs, to get the mass you desire it will be a lot of hormones over a long
period of time, there will be changes. I think a lot of us start out just wanting the boobs but unfortunately there is no magic boob pill.
But don't know of any place better than here for guidance.
