This was my original post on r/askteenboys, and I thought you all would like it

I'm 17 newish to a relationship with my boyfriend who is 19 and he wants me to choke him when we have sex. I am on birth control and he has a condom, so I'm not worried about a pregnancy. I'm still kind of uncomfortable with the idea of new things, but want to make my boyfriend happy. For the first few times we did it I was choking him with my hands, but he asked me to step it up a game and use something else. I'm a little confused, and scared to hurt him as I'm only 110 lbs and he's a little under 170. I thought maybe I should just buy a velvet choker, but idk. I don't think he wants to be strangled to the point of passing out. For reference we've been together for a few months and we've never had any "kinky" sex.
