I am looking for some ideas on how to bring sex back to my marriage..........someone help me please.......

My wife just doesn't seem to be interested anymore......Maybe it's the kids, maybe it's stress.

I've tried talking to her about it but nothing seems to work.

We tried setting aside 1 night each week as a special night but even that's fallen by the wayside.

I've tried massage and she complains about being ticklish. I'd even be quite happy to have just 1 night of only pleasuring her in what ever way she wants, but I don't have the opportunity.

When we do have sex she seems to enjoy it......She orgasms most times.....

I've tried asking her about fantasies....she clams up. I want to talk about my ideas and fantasies too, but without even straight sex.......I've got nowhere to go.

I'm soooooooooo frustrated. Any ideas will be appreciated.
