You misinterpreted. Handled maturely does not mean go into the mature territory of exploring sexuality and sexual identity. It means treating sexuality respectfully and with validity. Mashima just throws it around as gratification. The mere fact that he takes serious things like torture and death from pleasure shows that it is not just "heartwarming, fun action shounen". I find ZERO 'shounen' approach when it comes to such things. In fact, I don't even like seeing it in my adult shows. Again, something which even most fun ecchi are careful with. They keep a clear line to avoid pairing permanent damage or trauma with this kind of thing.

And you don't need to go to Magi or FMA, only Rave Master. RAVE MASTER. That is all. Oh, and it had confirmation of sexual relationships. Go figure.
