My SO was looking at porn while I was going down on him and he tried to hide it but clearly if he is looking at his phone while I am going down on him he either isn't interested or is looking at porn. I was the porn on his phone at one point and I am very uncomfortable with this. It's different if he is watching on his own time but when I am going down on him and he watches it just makes me feel so self conscious and makes me think I am doing a bad job.
