I wanted to ad to that my husband also had a very hard time with oral sex when we first tried this. As in being able to complete it by o'ing. He told me he had never been able to finsih like this. But then he had also said he never really had a woman who put forth much effort into this area. I took it on as a challenge.lol

One night I did it and told him in the middle that I would really love to be able to do this for him. It is one of the most erotic memories I have with him. He was standing and I was kneeling. It took a long time and took much patience from me. But we did complete it that night and the look on his face was priceless.lol He almost collapsed when he o'ed.
We have had many years to work on this. One thing I find that helps and he will O faster is...I have noticed he is visual. So if he doing things to me or has a view he gets excited a lot faster. Or if he is doing things to me and I am making appreciative noises. I did the same thing with hand jobs. I just told him I would like to be able to do this for him. That it very much turned me on. MY husband seems like the kind of man that just has a hard time with things being just for him sexually. It's like he thinks he has to satisfy me each time. He has always been great about foreplay until recently.
