We already had this kind of thread with the similar complaint,
but the whole point of being heterosexual is that if you are a guy you should be interested in the cute things and it does not matter if this is men or women.
it is pretty hard to make a cute adult guy without making it look like shota of some kind.

Also, if we discuss plain practical issues with boys, you don't have that much stuff to do with them, besides castrations because they just don't have any other parts. (Unless of course, you start treating them like girls )

If we try to put guys in the role of the girl making him submissive you need to make him look weak and that means cute. You probably can occasionally make some exception when a noncute person gets dominated but this is abnormal.

The guy being drowned in the human cum is not exactly very masculine thing this is more like girl in the male body
