Sadly they've technically only done it once
I guess I'm not missing much then. I was genuinely sad to stop reading this manga at chapter 10, it's really well done, but my frustration was greater than my disappointment. I guess my suspension of disbelief can't stretch as far as a 22 year old adult not knowing that sex isn't "stick it in and you're done". I sincerely hope they discover the "ins and outs" of sex (pun intended) and their relationship. I just don't have the patience to witness it as they do.
Yeah, I've seen many yaoi where it takes a while but there's always something big going on on the side, so I can shrug it off. Problem is, that's the ONLY thing happening with the couple. Do it or change the topic already.
The first couple is truly adorable, the art is beautiful and the story itself flows well, but I just can't drag myself through another chapter of cockblocking and ruined orgasms. To me, it's a pathetic as watching a man who is dying of thirst lap spilled water off the floor. There's nothing funny or endearing about it. That's not to say that there's anything wrong with the story or enjoying the plot, it just doesn't do anything for me aside from make me frustrated and miserable. It's really a shame too, because the characters are great, the writing is done exceptionally well, the art is very appealing and the translations are spot on. Everything about the manga is perfect, I just can't enjoy the main plot conflict. On top of that, it's not just a chapter or two, it's 14 so far and I've lost interest in whether or not they ever actually succeed. It feels like the entire theme of the story is that homosexual sex is fruitless and, for me, I find that idea repugnant. So, you won't find this in my favorites list or my re-read list anytime soon.
