so my partner (M) and I (F) are going to be having a threesome with a man i’ve been talking to. this will be both of their first time engaging in sexual behavior with a man (they are both bisexual) and this will only be my second time having a threesome with two men. i need some advice on sex positions with the boundaries/requirements that we have. none of us will be doing anal, i will be the only one being penetrated. also, the other man is bigger/more muscular than my partner, in case that gives an idea of how we can orientate ourselves. the other man enjoys being dominated sometimes and wants to be blindfolded at some point. i’m nervous about the logistics and i don’t want it to be awkward. help me!!
