Unattractive

So there's this new guy I like. I told him I found it hot when guys in all leather smoke. And I'm not against smoking per se I've smoked before but I'm not all for it either. Anyways so ever since that day which is two months ago almost everyday he sends me a video of him smoking. It's not even what I found attractive which is a very dramatic type scene from the play Grease hilariously or an old timey movie vibe.. he usually does it from a bong and I hate bongs or a joint. It's very unattractive that every video of him I am seeing him smoke. I don't mind him smoking at all but to me it makes it seem like that's his only personality trait and nothing else to offer. I don't think that is hot 😭how can I tell him to please stop sending me that? And I can't even open his messages if someone is around me I work with kids as well.
