I "play" with my boyfriends mates?

i'm 18 and i live with my 26 year old boyfriend and his 2 mates ranging in age from 21 to 24, all males. i only have full penetrative sex with my boyfriend but if he's busy im allowed to "play" with the others but their dick isn't allowed to go all the way in. they're all single. is this bad? is it normal? i dont mind and it isn't hurting anyone. and how can i tell or show my boyfriend that i want full sex with the others? *please no hate* this is my life.
