You can't tell me a spouse doesn't have a right to know these things about their spouse-to-be. How can you consent to something you don't know? If he's had lots of women in the past,  it's highly likely in this age of DNA tests and the Internet that one of these women will come around seeking child support, or one of his bastard children will want to meet their dad. How would that not screw up a "good Catholic family" he started later with a virgin Catholic woman?

Think of all the explaining he'd have to do to his legitimate children -- of all ages. How they have brothers and sisters they hadn't met yet for some reason. Think of all the birds-and-bees discussions that would have to take place before the proper time.

***How true, how true!  It absolutely tickles the you-know-what out of me, that DNA tests now allow paternity to be proven, as part of the larger picture of gaining knowledge of one's family tree and hitherto unknown distant relatives.  You always know who the mother is, but as for the father... how many men have been duped into raising another man's child?  Isn't that cuckolding in the extreme?  That's why I say, birth control (and even more so, sterilization) allows both husbands and wives to make fools out of each other, because they can have all sorts of sɛҳuąƖ exploits without ever getting caught up, or having fear of unwanted pregnancies.  But what about when it fails, or one or the other strays in a moment of recklessness and doesn't use the BC?  A woman can always pass off the child as her husband's, barring any drastic difference in appearance (most of all an obvious racial one! --- "I can explain, dear, my family was Dark Irish!" ) --- and the man who fathered the child, without paternity testing, is likewise scot-free.

Now here's a soap opera for you.  Recently I got my son an AncestryDNA test, like the one I took myself about a year ago.  Sure enough, my son is absolutely, positively, infallibly mine, but... lo and behold, in the past month or so, guess what, I've got a new cousin out there, that I'd never heard of before, and I know who all my first and second cousins are (or I thought I did!).  The number of centimorgans (DNA markers, or something like that) is right on the cusp of his being my full-blood first cousin, or a first cousin once removed.  IOW, he is the son of either one of my four blood uncles (more likely), or one of my male first cousins (less likely).  Three of my four blood uncles had, ahem, issues with fidelity, one very much so.  My male first cousins, all over the map, from relative chastity to absolutely whoremongery.  Interesting family. The question "who could his father have been?" has been a huge topic of discussion with my parents the past few days.  (I have long ago drifted apart from my extended family, that happens when people move, don't see each other, and die.)  For us, it's merely a point of speculation. But think about the poor man who is my hitherto unknown cousin! In all likelihood, he's gone his whole life, thinking that his father is someone that he really wasn't!  Talk about getting emotionally hit by a semi-truck!  (My son knows it all, knows everything about "the birds and the bees" that it is possible to know --- very curious kid --- and I was able to use this as an object lesson in chastity, IOW, "keep it zipped!".)

Oh, and if I were a young lady, I would definitely do my DUE DILIGENCE and look into the man's past. Look him up on social media, pose as a high school friend and see what you can find out, etc. I'd probably pay the $30 or $60 fee to do a background check. Or a few hundred dollars for a private investigator. Think that's excessive? You can't be too careful these days. We're talking about avoiding a life of misery, loneliness (divorced but can't remarry), poverty, strife, etc.  I think a few hundred dollars would be well spent to avoid that! Oh, and as a bonus (since you never married "the wrong guy"), you might also GET a nice Catholic man, loving family, beautiful Catholic household, many beautiful well-raised Catholic children, grandchildren, etc. as a bonus! A few hundred dollars sounds like a bargain now...

***You will never waste money on a good private detective.  Without getting too specific, I had reason to hire a PI, as well as an attorney who obtained some information for me that, let's just say, I'm not supposed to know.  It was to protect a family member.  Cost me $450 in all, and boy oh boy, was it ever worth every penny! If you ever even think there's an issue that needs looking into, do it.  Hire that PI.  I know.  How well do I know!  And there was another incident in my life where I didn't hire a PI --- didn't want to spend the money (oooh, that's right, gotta save that money, don't spend that money) --- and I could have saved myself a lot of heartache, if I had hired one.  It's water under the bridge now, but it could have saved not only me, but people I care about, a ton of suffering.  Let me repeat.  Hire that PI.

Oh bullshit. I've been hearing that crap about women "riding horses or playing sports" for decades. Almost no women riding horses and very few women play sports. Also, what kind of sports would break a hymen?

People have cited two priests that have said otherwise. That's much more compelling than your opinion.

"Virginity tests" are impossible to do on a man.  The conventional wisdom nowadays, is that demanding physical evidence of a woman's non-virginity (i.e., intact hymen) is an injustice, because any number of things can happen --- she might be born without one, it might be defective in some way, it may have been torn open through some physical injury, or what have you.  

Again, if in doubt --- or maybe even if there is no doubt --- just do yourself a favor, and hire that PI.  If you don't, and it blows up in your face later,

If you are so inclined to hire someone to spy on her then she should not marry YOU. I would never trust a man who had such little trust in me. Better not to marry at all. Or find another man.
