I simple LOVE when the seme is manly, muscular, even bearded xD, possibly violent~rough or evil is lovely as well
But in general just manly and big, strong... bigger than the uke, but NOT like Okane Ga nai, more like just much more muscular.
But yeah, any suggestions will be loved x3

Possibly you might like some stories by Higashino You the semes are always buff and manyly, but probably not the 'rough bearded type' you're looking for.
Also possibly Kanashii Doubutsu? But it isn't finished. I'll have to sift through my bookmarks later to see if I can add more, but these are what I can think off the top of my head. >.<

w< Ooh thank you so much, these seem very good!~I've read Katsubou no Manazashi, and dare I say, I loved it x3
I don't exactly crave for them to be bearded, that's just a funny plus xD But thanks a lot, if you find any more, please do post them here <3 😀

Check out this thread, I have suggestions for a similar type of seme there. You might also search for 'manly' seme threads.
