My Crush

There’s a guy I’ve known for maybe 4 years now and got the most part he’s cool & nice looking to me but I never gave him the chance to hang out with me more because he wouldn’t say much to me in person but over text message he would , anyways I recently had a conversations with him and he asked me “why did U used to say I was a baby “ and I told him straight up it was his actions he didn’t talk to me much and he told me it was because he’s younger than me (3/4years) he didn’t want to say the wrong thing but now that I’ve talked too him more and it seems he’s more confident . I WANT HIM SEXUALLY but I want to take control of him , should I express that to him that is what I want or keep it to myself ? And he’s a sweet little gentleman , he’s been asking for my number again for months & kept trying after I’ve turned him down numerous times before giving in
