Asking your mans to sext you 👅💃🏽😏

Hey guys. lol so I'm dating this super sweet guy right now and I mean he is really sweet and caring. I can definitely see him as a boyfriend. He is a tab bit nerdy and I even admire that quality, but he just isn't as sexual as I am😬. When we text I sometimes throw little sexual innuendos at him and he completely misses it lol. Literally he wil pick up on it hours later and say "oh!" "Are you saying you want to met up? ;)" I think it's really cute that he isn't a super experience guy and isn't a fuck boi. Anyway I'd like to ask him to start sexting with me and I'm a little nervous. Should I keep things the way they are (which is nice and slow) or should I ask him to try sexting with me. If so how should I ask lol

Update he's super cute at sexting. It's like really proper but I like it
