OP: I find it hard to believe that all that extensive sexual experience of yours is so useless in the face of your current challenge. You cannot convince a pregnant woman that she is completely awesome now and that you are absolutely doing to do her? Think hard . Do something. Basically, you like her, she likes you, in the past things were OK, and now you cannot help her get out of what you dubbed "her going subconscious"?? Pregnant women do have sex - why should she be an exception? You do not have sex addiction, but you do have difficulties with creative problem-solving. There are no 12 steps anonymous groups to help with that - you need to think think think and ask around for ideas, process the suggestions, adapt them to your situation, and implement them. Can you open another thread (on here and on the forum for men) about how to sweep a pregnant lady off her feet and carry her onto a king size bed for some action?? That is what you should be worried about - addiction you do not have because you are fully functional. While the term "sex addiction" is highly dubious, if we accept that sex addiction exists, we would need to apply the same yardstick to it as to other addictions, and thus would need to look into whether there are functional impairments. You do not report any functional impairments. You just lack creativity. It could be due to the dichotomy you maintain between random strangers and your partners to whom you are attached. From what you have written, you are inhibited, to some extent, when you are having sex with an emotionally meaningful partner, but when it is with a stranger, things are great and you shed all your inhibitions.

So now your woman is going through a strange period of inhibitions of her own, and instead of trying to break through them you defect. But that is boring. Challenges are needed, from time to time, to lead a meaningful life. You are now up to the challenge of having sex with a pregnant woman - find ways to overcome that hurdle and you will be that much happier and more proud of yourself in the long run, even if the marriage, sham as it is, is going to end soon.

As for the marriage - it really is not a marriage. It is a formal arrangement in which you entered to placate her parents.
