I don't think he is going to have sex with anyone else...I think he is going to run away now because he is too much scared of allowing himself to be happy and loved by others. So I guess we will have a little bit of struggle until Doumeki finds him and opens his heart. An "I love you Doumeki" is going to be difficult as hell I am afraid...
I hope hope hope you're right; none of us want him to ever have sex with anyone else :(
and I definitely agree with you regarding him running away. Based on what we know of Yashiro, it seems almost inevitable that he puts up resistance with all his might, unless we are proven wrong which would be wonderful, but I don't think so. He's not going to accept Doumeki's feelings nor fulfill Doumeki's expectations that easily, so this is still a long ride for us （￣へ￣）
No, I don't think he is going to have sex with anyone else...and in case there is an "attempt" to it, I think just the touch of the other guy is going to make him feel like puking...just the reverse case. After realising how it feels to be touched by someone that loves and cares about you, any other kind of touch is repulsive. As he didn't get that until know he could not know. But now he knows, so if there is an attempt I bet he will end up pushing away the other guy (๑•ㅂ•)و✧
Ladies and Gentlemen, THAT is what lovemaking is all about! Even though I'm dizzy with happiness, I'm afraid that Yashiro's determined look at the end is like "here comes the angst"... Let's brace ourselves for the dreaded "separation" and/or worst, Yashiro having sex with other people in order to to re-assert himself from the vulnerability Doumeki's lovemaking made him feel, to feel in control again :(
