i need advice!!

A week ago i asked a boy to hookup (not sex, just like makeout i guess) and we did tonight. Basically me and my two friends and his friend came over to my friends house and after a while we went upstairs and hook uped for AN HOUR. We hooked up and like it got pretty serious (no hj or bj, j like shirt off). Like we aren’t gonna date (i think) but we are just to friends that hooked up for an hour and i wanna do it again but i don’t know how to tell him that. Any advice??
