op, how did you join?
is it invite only?
if that be so, you can invite and decline based off your own discretion.
if you feel ya homie is not mentally equipped, you have your answer.
tell ya homie y'all not accepting new people right now. and y'all get togethers are members only for the time being.
or, if there is a couple in ya club that swings, tell ya homie that you can connect them together, so they can start small instead of jumping into the deep end. facilitate the exchange of their information, then wipe your hands clean and let them take it from there. if shyt happens, that's out of your hands.
and finally, stop discussing your sex club escapades with ya homie or anyone you wouldn't invite to ya parties. cuz when they get interested and ask to tag along, you've now put yourself in an uncomfortable position to have to turn them down. the only folks you talk about this shyt with are those you'd consider inviting.
