Hi, my partner is the most loving and noble man l have ever met, but when he drinks his mood changes like jekyll and hyde, from very happy and placid to aggressive, arrogant and trying to create an argument to storm off, he knows l am against drugs very strongly, so l dont think he would admit it to me, also, we have an argument and he says he needs to be on his own a while, how can l tell for sure. Sexually, he usually doesnt touch me until he has had a drink and then fails to ejaculate, even after quite some time, he is a big drinker on weekends, so lv always put it down to that, but am beginning to wonder now, any ideas. thanks
