Do I stay with my BF or not?

Me and my bf have been going out for a month now and nothing has happened.. we dont even hold hands.. and I still like him but the relationship is boring and there is this other guy lets call him T who is 17 me and my bf are both 15 and well T has had a gf for awhile but likes me a lil bit.. so idk if I should stay with my bf or go with T even though right now he has a gf.. btw I wont see my bf all summer but will be hanging out with T in his town (he lives in the same town as my gma and thats where I stay in the summer) and will be hopefully teaching me different things so idk I just dont want to hurt my bf
