I've had an awful cough for the past week and a half, so I've been using cough suppressant to keep it in check. Last week I was having sex and I just couldn't cum at all, and then when I tried to get myself off, it was basically impossible. I've masturbated a few times since, and it's ridiculously difficult to have an orgasm, and when it happens, it really is underwhelming. Has anyone else had this experience? I'm pretty sure it's either my illness or the dextromathorphan, because this is pretty strange for me.
