arguments

my boyfriend and I started talking about threesomes while in the mood and he wants 2 girls and i wanted to try 2 guys and we got into this big argument about how i want another guy and how i should just have sex with him but i should be equally mad he gets two girls sucking his dick? but its like i didnt, and I'd do whatever makes him happy but i wanted just ine threesome and he dislikes the idea about it. Am i wrong to know that this is unfair?! he says its weird to see other guys junk but it's halfly as weird to see a girl naked. but idk i do so much to make him happy yet he wont let me have a threesome ?!?
