Should i give him a head...?

I have this guyfriend ive known forever! He use to like me and tried me but i rejected. Now its three or four years later and hes sorta a drunk *** not mean but just into drugs and out of grades? He flirts with me and i sorta like him. Im not sure why but i really love his personality! Hes DEF not cute though. Hes ****** a phew girls in the school and gotten one blow. I really want to make s name for myself and give him head and then chances are him and his guyfriends will probly like me. By the way hes fairly popular. And also im gonna be a freshman and the way our city works is you cool if you do drugs. your freakin great if you have gone out with a shitload of guys and you makeout with whoever.. But your a f u c k i n beast if you give someone a head or **** them. Should i? I know its wrong but i dont care!! Think as if you were me.. Thanks u guys:)
