Crushhh

Soooo basically there’s some guy I met at school and he’s insanely hot to the point where he makes me nervous we’ve talked a few times here and there and even flirted and talked around at one point so basically it died off but just recently we started talking again, so he throws subtle flirts at me and I do it back but I feel like the conversations dying out again and I don’t want it too also I kinda want him to know I like him and potentially wanna hook up but don’t want to flat out say it what should I do??? HELPP

Also how do I go about Sexting him if I’m nervous as to how he might react
