Hidoku Shinaide
This manga I enjoyed, mostly because of the romantic parts but it does include a relarionship starting after a rape. I've seen many people dislike it because of the beginning and such, but if you try to at least stick with it until volume 4, you'll start to see the real love.
Kawaii Obaka-kun
Uke-chan in desperate need of money decides to try out prostitution to make up for a debt, and unknowingly meets a love interest?! Hot, steamy and very detailed adult-time scenes with a drama and love typed added in.
