beautifulswan Intimacy, affection and sex, amongst other things, are very, very important parts of a relationship and in a healthy relationship, important things like this are discussed, even if they turn into difficult discussions that are impossible to resolve.
It may well be "her choice" but, again, in a healthy relationship, these choices can be discussed. In unhealthy and unequal relationships, choices are imposed on the other partner. Whether those choices are financial, physical or emotional, it makes no odds - the outcome is the same - Inequality in the relationship.
It is shocking that some people effectively tell their wife/husband/partner "that's just the way it is, live with it", but it happens a lot - and refusing to discuss the issue is exactly the same. IMO, whatever the issue is, if that is the stock response, then it's a clear sign of an unhealthy, unequal relationship.
The very fact the it is an "issue as personal as this" makes it even more important that it is addressed together
