I just love uke dresses in drag/drag queen so much. I searched with gender bender genre but it doesn't really help... I don't like girly uke though, the more manly he is, the more I like it, it'd be the best if it's bara (musculine uke)...

Do you know manga like that? I've read some manga but of course it's not enough sob please help~

Here are some of the cross-dressing manga I've read
Sabishigariya wa Yume o Miru chapter 4 and 5
Kocchi Muite, Ai chapter 5
Udagawachou de Mattete yo.
Harem de Hitori
Henshin Dekinai
Houkago Edge

Also you can try the "cross-dressing tag" in advanced search

And this is what I got after combining the tags "cross-dressing" and "bara"

I haven't read any of these so I can't say if they're good or not.

OMG thank you very much, there are manga in your recommendation list I haven't read!
Thanks again xD I'll try them~

You're welcome : )
I'll try to see if I can find some more.
