I don't think Maluma would have a relationship with another guy, I don't even think he would like to experiment with one.
Also the OP left out the last part of the article whis is very important, I will try to translate the best I can:
And there are other publications that also claim Maluma said very similar things, that he is not gay and doesn't have a relationship with Ricky and that he loves women but that he has a lot of respect for the LGBT community.
