Is there any uke who is in the charge of dirty talking or like taking the lead?
I wouldn't mind a shy seme also ^^ but how the seme is really doesn't matter as long as he isn't too annoying or something like that.

These are titles you could find interesting, as for dirty talk, idk how much hardcore do you want so..
Mirai no Kioku
...Virgin Love and ...Junai no Seinen (sequel)
Cold - Zettaireido no Koibitotachi - uke's pretty wild later
Hard Core Heart (BDSM, threesome)
Sokonashi Freefall Romance - 2) Ore to Kareshi to Aitsu to Kare (BDSM)
Vanilla Boys
Kibishiku Aishite (BDSM, threesome)
and many ukes from Minami Haruka are like that, for example: Senzoku de Aishite, Sweet Meats, Making Love Like Newlyweds, Love Cure
