Whenever I kiss a girl, I usually have my mouth in a small opening, and tend to use light tongue and an occasional gentle pull on the lower lip. Ive been told that im an excellent kisser from pretty much every chick ive kissed, so Im pretty confident its true. Problem is, lately ive been encountering girls that seem to be trying to suck me in head first with thier mouth. Its not attractive to see a girl with a mouth wide open coming in for the kill, and it really screws with my concentration. Its a total turnoff, how can I politely tell them that they suck?
