Funny I don't remember wishing for tits and/or horny, I said I hope he gets a waifu (Or Husbando if he swings that way). Big ol difference there.
Your assuming representation with no basis though, also love interests don't have to be explicit like why are you guys instantly jumping onto the "Drop on his dick" stance lol I never said you can't have asexual protags/characters I said that unless stated I'm not gonna assume they are cause why would I assume the lowest percentage choice?
As to the second part relationships can happen with that kinda problems (I can't think of a way to describe the list you have better so sorry on that, no offence intended) plenty of child safe series have done it so why suddenly can't this one? Am I glad it's not some harem with women fawning over MC's dick? You bet I am, doesn't mean I wouldn't want to see him have a full happy family in the end.
