Regarding "The only lingering issue is that I find the artwork drawn is still extremely attractive to me as opposed to the real life thing, and I want that to end too, but I just don't know how to stop enjoying it.", there is an approach called desensitization and there is also a very helpful paradoxical approach. Instead of forbidding yourself these pleasures, indulge in them as much as possible, doing more than you actually want, and maybe you will reach your limit and become bored of this kind of art.

I would also enroll in a good art history course (online?), ideally one that traverses many centuries of nudity in classical art. And take it very seriously, do your homework, complete the assignments, read up on the personal history of artists and of their times and social circles.... really get into this. Both paintings and sculptures. And as you go through examining painting after painting, ask yourself if there is anything that speaks to you, anything that you can find relatable?

This will be skewed more towards female than male nudity, but you will still find enough male nudity. So, it should give you some material to try to determine if you are attracted more to male or female human form.

And you do not even have to make it about nudity. You can examine, more generally, human form in art.
