Do most people sexually fantasize about their crush?

I dont sexually fantasize about my crush, rather fantasize romantically. It feels weird to me and brings me guilt to think about a crush who you dont know if they like you in those situations.

 

I sometimes do, but after awhile I feel like I disrespect her and stop. I much more enjoy imagining her holding my hand and stuff.

 

No I dont fantasize him sexualy. I just fantasize going on a date with him and holding his hand.

 

I do.
