filippino coming to Spain

hi, i'm a spanish guy. my filippino boyfriend and me have decided that it's time for him to come, after visiting him several times in the Philippines. i don't know how. he wants to come and study spanish, because without knowing spanish he could never stay. so he needs a student visa. but i want to marry him because he could stay here with me, we don't know how to do it, wether he has to do something before the wedding there or not, or what else. can we get married in Spain if he came with a student visa?? i can't marry him in any spanish consulate in his country because being two guys we're not allowed, so it's very confusing for me.
