Sexting.. what if he's not into it😬

So I sometimes get into mood when I wanna sext with my boyfriend but then I start to think things like what if he don't get into it too or what if he thinks it's weird or something😅😅

We have never sexted before and we have been dating over a year now and I would like to somehow spice things up🙈 this is one way I was thinking of doing it.

Should I just sext him or should I talk about that with him like does he want to sext or not?

I feel really embarrased about asking these🙈🙈
