Need versus a want?

[MJontheMend]

I'm going to give you a practical answer. You know that your W doesn't want to give you a blow-job. She would be overwhelmed by this request. I know that my daughter doesn't want to clean her bedroom. She would be overwhelmed by the request. The way I typically get her to do it is by breaking up one big job into a lot of little jobs. Throughout the day, I'll say things like "Now go upstairs and bring down 20 items of laundry" or "First bring to the kitchen anything that might go rotten.". Eventually by the end of the day we get to the part where she is proud to let me inspect her room.

If I were you, I would apply PM principles with the goal of getting a blow-job, but I would do it in "baby steps" (I'm sure all Bill Murray fans are laughing to themselves).
First tackle her general penile revulsion. Figure out how to make it her friend. For instance, if you are at all clownish, you could make it talk to her or you could make her feel sorry for it, if you demonstrate how easily it can be hurt or if she doesn't like the looks of it, you could see if she might find it more appealing if she touched it with her eyes closed. Next you could see if you could just get her to kiss nearby areas like your belly or your thighs. Eventually you could convince her to kiss it and then perhaps to kiss it while you jack-off. From there you could progress to just sucking, licking the head and not swallowing and then either a full blown blow-job without the swallow or just a headjob with the swallow depending on which is least appealing to her. Hopefully this will lead to a completely successful confident blowjob someday. Please don't be insulted if I offer one bit of advice for you. The number one absolute no-no any guy can do in bed is to put your hand on the back of a woman's head when she is giving you head. As far as I know, all women HATE this.
