I’m purple he’s grey

The other day my boyfriend asked me if I would be mad if he hung out with people and did things while I was preoccupied. I said “no as long as you’re not hanging out with other girls without me because I know you wouldn’t like it if I hung out with other guys without you.” and he said he wouldn’t care as long as he trusted them (meaning his brother and a few his close friends) and so I said “okay then you can’t hangout with girls unless i trust them.” and he argued with me saying that there’s a difference between him hanging out with girls and me hanging out with guys (because it’s more likely that a guy will try to take advantage of me). I still feel like if you don’t want me doing it then you shouldn’t do it to me. It also makes me uncomfortable that one of his friends is a girl who has made it known to him that she wants to sleep with him (yes i’ve told him it makes me uncomfortable). He also rarely tells me about these friends that are girls and never invites me to meet them nor do they seem to inquire about me. am i wrong for this? am i being crazy? is there a reason he seems so insistent on hanging out with his friends that are girls without me?
