Wow Mew, that is such a ridiculous post, and hugely disappointing coming from you. Basically, your saying that varying degrees of severity can’t exist at all? maybe his numbness wouldn’t come and go from drinking alcohol, if it’s as simple as that - maybe he isn’t experiencing real numbness because I think every man loses sensations when there drunk, hence the reason we all joke about taking too long to ejaculate during drunken sex. However, there is every possibility that he is experiencing slight numbness normally and being drunk just amplifies it.
To qualify as having ‘PFS related numbness’ it can’t vary? that’s just bullshit and you know it. If our conditions have anything to do with hormones, fluctuation is EXACTLY what will happen.
