Maybe it's because Diesel is not really ready to embrace the fact that he is falling for Ein? Idk. Maybe he is not ready to let whatever he felt for Yanek, go. The thing I like about Ein and Diesel's relationship is that Ein is letting Diesel figure things out for himself and not taking advantage of him in his confusion. My guess is that he is doing what makes Diesel comfortable. I feel that once Diesel is ready, their relationship can blossom into something even more beautiful (including being able to do face to face ;) )
I think about this myself too. But it s always Ein, who says to Diesel to turn around and decides about doing it from behind. From my perspective this position can be hard for Diesel, cause when he was chained to the floor in church basement he was raped like this, so doing it in that way can remain him about priest.
In chapter 36, when Ein and Diesel are face to face in intimate moment, Ein told Diesel to turn around and leave hips. It s sounds kind of cold, but we see only 2 sex scenes with them, so it can be only coincidence.
I think problem with Ein is that he rejects wolf part of Diesel. Ein just talking about Diesel disappearing during day and leaving him. I remember in chapter 17, when Minsuk told Ein, that he thinks, that Bexan doesn t disappear, he s still is this same person, only in dog body, Diesel looks on Ein with hope, that he would also start look at him like that. In that respect, for Diesel was easer being with Yanek, who rather don t have problem with seeing Diesel as person in both his form. Also Diesel seems to has remorse towards Ein, when he turn in dog and leave Ein alone, only cause Ein thinks about this in that way. Poor doggy.
Is it just me or does it seem like when Diesel and Ein have sex the mostly do it from behind? So far we have seen two short sex scenes of Deisel and Ein and they have mostly done it from behind when it comes to penetration. But when Diesel was having sex with Yanek the scenes shoe him facing Yenek and embracing him and being penetrated from the front. Does these scenes and how they have sex have a deeper meaning behind it? Or am I thinking too deeply into it?
