Hi folks.
I guess I have been whining a bit about this before, but I just wanted to "air out" some thoughts.
I frankly don't think my wife and I will ever have a "normal" sex life. I am a relatively horny (OK sometimes VERY horny) guy, and she seems to lack libido almost entirely. I have tried to pinpoint what exactly the problem is, and I found a number of things:
-She often feels that it hurts. She sometimes blames my "large size" but I think I am rather normal. Lubes help a little, but she still does not enjoy it.
-She is extremely ticklish. Sounds like a strange problem, I know, but it made her recent trial run with a vibrator a fiasco. It also makes touching her body (particularly breasts) difficult.
-She has some body image issues. I like her body, but she is shy about it. I know this can kill the libido for some people, but it's not the whole story. A few months back she was in very good shape, and proud of it. It still did not make her horny, but later putting on some weight while she was ill (+Christmas) certainly did not help.
-She simply doesn't think about sex the way I do. She can go for months living happily without it.
For the record, we don't have kids. Would have been a nice excuse, but no.
Some might wonder why we stay together. Good question, but I guess you could say that we are firmly "emotionally attached". We have gotten each other out of some bad situations before, and we would do it again. We have traveled the world together, and I sometimes feel that I would never find anybody I would rather do that with. In some ways, we are very similar. We're both a bit "bookish", non-religious, and a bit childish at times.

She is more than willing to experiment, as she is almost as curious and inquisitive as I am. This is why she has been trying vibrators, and even coming with me to strip clubs and some other "kinky" stuff. It never really made a difference in the long run though.
I sometimes wonder if my situation is far more common than we think. You hear stories of 1st World War ladies who were told to "lie back and think of England". You could almost say that we have tried that too, but it's not exactly my idea of a good time. I frankly think it's a turn-off when I know she doesn't like it. She is also not good at hiding her discomfort
I guess this thread can be for people who want to vent a bit about their similar frustrations. I know there are a number of couples here with the roles reversed (him lacking libido, leaving her horny and frustrated). Helpful suggestions are also welcome, of course, although I am not really expecting a "miracle cure".
