Did you have a question? Your title and description are statements, except for the rhetorical 'Am I crazy?'

As to sanity--consider it as a matter of deviance from the arithmetic mean with respect to some nebulous basket of attitudes, habits, confessions and professions. In which case, you are definitely unusual with relation to the people of this age. Whether you are to be considered mad would depend on whether your peculiarities are so extreme as to be bothersome for the rest of society. In the case of your celibacy, no one cares enough to commit.

To answer the question that I think you might be asking, I'd want to know more. You'd need to know more. Where do you end up in terms of men's assessment of marriageability? While that's going to vary from man to man, the usual measures of men's revealed preferences are youth and beauty, followed by femininity and continence. You are past the age at which most women will receive the maximum of superficial attention from men.

If you are not being asked out much, it implies either that the men you are surrounding yourself with are too distracted to pursue you, or that you have not successfully caught the attention of someone serious, or a combination of the two.

It will not be possible for you to court for sexual attention and for chaste marriage at the same time. If you choose to court for a chaste marriage, it is necessary to accept that a possible outcome is that you may never marry. Is that something you are prepared to accept, fully and without deluding yourself?

If you choose to offer sex to a man who is not your husband, there is a real possibility that man will never legally marry you.

If you wish to court for marriage, in addition to the responses of various other posters (put yourself out there, etc.), consider pursuing the acquaintance of godly wives who can model a good marriage, and make it clear that you are neither playing the field nor intending to sit this lifetime out. A woman who believes in you will be very willing to set you up for success.
