How to kiss/tell him i like him?

okay so i really like this guy and he lives across the street from me we go to diffrent schools but we have been knowing eachother for 3 yrs now. i have another gurl that lives next door to me n she said that he likes me. do i ask him if he likes me? or do i tell him that i like him? and if he does like me we might kiss cuz hes that kind of guy. it will be my first kiss so... how do i do it? how do i hint that i want to kiss him? ik that your supposed to look at his lips than his eyes but anything else after that? and after what do i say? and please dont say anything mean! thanks!
