I would just like to point out to you, that by your stated criteria, someone who made a mistake and married someone in the Catholic Church, later got divorced and the Church recognized an annulment is not worthy of you, while someone who may have been highly promiscuous, but never married, is acceptable to you. This is what may be deferred by your definition if I am understanding it correctly.
If your definition is you want a male virgin at 40+, then that is certainly your perogative, though I have no idea how you prove or disprove it in this life.
Being a virgin isn't a big deal with me. Actually in both of those scenarios I wouldn't like either guy. I prefer a never married guy who may or may not be a virgin but didn't sleep around either.
