As title says. But, I do not want any rape, incest, shotacon, or lolicon, though. Nothing like that please. ^^ What I am looking for exactly, is people choosing to lose it. Preferably, at an older teen- young adult age.
Well, pretty much every one of Yoshihara Yuki's heroines are virgins, and I don't think any of her smut is rape. But loss of virignity isn't dwelled upon in many of them. Aisuru Hito comes to mind...
