i need some advice

so my bf and i have been dating for the past five months and we've both been crushing on each other for years before we started dating. i really really like him and he's so kind and sweet but my family thinks he's gay. his voice is not at all deep and his friend will sometimes tease him. his voice is the only thing that even seems remotely gay about him. he's so affectionate towards me and always wants to snuggle and give hugs and kisses.

his voice is the only thing that even seems remotely gay about him. i don't really know how to say this because i don't want it to seem offensive but usually when a guy is gay there is like and accent or something and my bf doesn't talk like that. his voice is just not as deep. and his friends will sometimes tease him about it and it's fine.

what my family thinks is important to me but my boyfriend is not gay. i don't know how to make my family understand that.
