No I don't have data points
Empiricism is not the only valid source of truth breh. Most of what you hold to be true is not empirically verifiable.. logical deduction, testimony, anecdotal evidence etc are all valid sources of truth. Even if I were to present you with data points, you'd have to rely on testimony (i.e whoever conducted the study is a trustworthy individual so we can trust the data.. in actuality we have no clue).
But lets not get into epistemology.
We're talking in the context of marriage or long term relationships. Of course guys will smash anything at least once.
Do you believe, based on your 50+ years on earth, that the average modern man wants to commit to a woman who is sexually "boring" long term? Terms like "dead fish" were invented for a reason breh.
Let's start at the bold part. You are implying that a woman who is a virgin is going to be boring in sex the rest of her life? In my 50 years on this planet, every women from hoe to housewife started out as a virgin. Every woman who is sex positive to frigid started out as a Virgin. So how can you make any determination that any particular virgin you come across will perpetually be a "dead fish" in the first place? How in the world do you make that assertion and speak about truth in the same post?
Second, if you are going to say something along the lines of the average person is blah blah blah, then you definitely need to have some data collected to actually back that assertion. If you do not, then it only remains in the realm of your opinion born out of your limited information on the subject. You can't speak on what the average modern man thinks of virgins, because you have not collected any data to even determine what the modern man thinks. The best you have is anecdotal evidence from those you have come in contact with and discussed this issue with. By what you have written in the part I bolded, your whole premise is easily destroyed by the fact that every woman, and I mean every woman, starts out as a virgin.
Also, a woman being a 'dead fish' in the bed can have multiple reasons that have nothing to do with her experience in sex. Could be an indicator of past abuse, could be an indicator of her not feeling you that much, could be an indicator that she is just lazy and use to the man doing all of the work. There are more reasons, and none of them requires the woman to be a recent virgin.
So the original assertion was modern men can not handle a Virgin. A Virgin /= a perpetual boring lay, and every woman you feel are exciting were once a virgin themselves. Everyone was a Virgin at one point in their lives.
So I have to ask you a question back. Do you feel you need a woman turned out by another person before you feel she is worthy enough to be in a serious relationship with you? The way you tried to equate virgin with 'dead fish' seems to suggest that may be the case for you.
