I'm a bit hesitant to ask about this one because I might be the only one who has this problem, but whenever I give head, days later I have problems breathing like I'm congested. Before anyone starts yelling "UNCLEAN!!!" I've been going through this for as long as I've been having sex and I've gone to the doctor multiple times, so no STD's here. I recently had a horrible asthma scare and was in the hospital for a couple of days but am thankfully clean and clear for the time being. The downside is that I'm totally scared to perform oral again because I'm afraid I'll start having congestion problems again. Can anyone help me and shed some light on my situation?
