Welcome to the site yotomit. I think this might be a place to explore the ideas of fantasies. I saw what you posted in chat, and it depends on what you mean. If you have fantasies you want to explore with your wife, you could try talking to her about them. It sounds like you are afraid of what you are feeling and how she might react. Well certainly, the 'force' we talk about is fantasy and role playing, and we do not advocate real rape in any way. I advice just try and talk to her about role playing starting with something mild.
