Nice Boy / Girl Syndrom and sexless marriages

Somebody has introduced the problems some days ago, about many relationships and marriages being sexless, where "sexless" means less than 12 "couplings"/year.
The nice boy / girl syndrome is when he / she are wonderful, devoted partner and the other loses interest in having sex with him.
QUESTION!
- Are you a nice boy / girl and you are also in a sexless marriage?
- Have you ever considered this as a reason or have you better thought it was just "stress"?
- Do you really want to turn into a bad boy / girl to be cared upon by your parnter as it should be, or you better go and look for another one?
- How much this luck of intimacy affected your love?
- Last but not least... have you got an idea of why you are still inside such a sexless relationship? Can you explain to you and to us why are you caught and still remain therein or are you already trying a way out?
Thank you for answering, I will rate everyone tomorrow.
