Let me start by saying this is my second go around with a pmo guy. I have a habit of attracting it for some reason. The first time through the guy was too deep entrenched to go through the process of getting over it. So while I know some things that do/don't happen, I didn't experience everything. So the flatlining thing...my current guy had a pmo habit. Gave it up, pretty easily. Saw the flagging erections with him. Not soft, but not 100% either. Now we are six months in and suddenly it no longer works. He can get erect but as soon as we start to actually engage in sex, it goes soft. Side note, more often than not it is fine with oral or if he makes himself erect, just not for sex. It goes soft almost right away. He has used a handful of excuses, tired, age,(38), sore muscles. I don't believe the excuses mostly, but know that it is a little pointless to call him out on it. We haven't realy talked about it, bc I don't know how to really. But we are now at a point where he just wants mutual oral, but hasn't even tried to engage in sex again. I know flatlining is a thing, I just thought that it happened much earlier in than six months. Is it possible that this is what it is? My brain is a scrambled mess. I'm trying to be patient with it, but it's really hurting me. And advice. Or some general answer would be appreciated!
