What’s the name?

So I’m looking for this one hentai manga I read years back. It was about a cross dressing boy with a big harem of girls (I think) and it was hilarious af. I think the MC was a popular idol whom everyone thought was a girl cuz of his cross dressing hobby but at home he had this big mansion where he lives with all these girls and all they do all day is sleep with each other. But it was so funny I remember.
I think they also went on vacation once together to the beach.
