only advice i will give a fem from a fem is if you are at all in any doubt then dont try anything .... but if you do want to try something then perhaps at a club may be the way to go as if you get at all nervous then you can leave the room and no one is any the wiser that you have cold feet,,, just make an excuse like you need the toilet. clubs have private rooms so you dont need to be in public view. most males at clubs, i have found, are utterly respectful and if you mention you are new and nervous they will be even nicer and more curtious. but if at any time you feel things are getting too much just say stop and i am sure that no matter where you have decided to play then any decent play partners will respect what you want
you need to talk talk then talk some more.
you could be opening a can of worms.
what if during you decide to say no, will they both be cool with that.
is it going to be someone you know? will they talk out of school?
what if you say an out right no, will your b friend be looking else where, or is there the veiled threat/worry that he will go off and leave you or go off and do it behind your back?
what if it develops and he wants to have 2 women?
i guess you must be interested to pay to join here or you could have researched this without cost.
