For the unknown time, there won't be any sex in DxD, DxD is an ecchi series. For starters, if we allow Ishibumi to write as he wants without the publishers' interference, Issei might have lost his virginity by now. Like in Volume 5, Issei was supposed to suck Rias' breast to power up but the publishers decide that it is too sexually suggestive and had it changed.
