It’s estimated that 1 in 5 children are not the biological offspring of the “father” - the classic term is cockold … from Wikipedia: A cuckold is the husband of an adulterous wife. In evolutionary biology, the term is also applied to males who are unwittingly investing parental effort in offspring that are not genetically their own.

If you want to be less obvious about it, I would suggest finding sexual partners with similar physical characteristics and racial background as your future husband. I’m sure I don’t have to spell out the reasons why that’s important.

Of course, another way to go, would be to find someone else to marry. Although, obviously, you have chosen this man for a reason - you just don’t want to have his DNA as part of YOUR children.

You do run the risk, as the point where one of you decide to divorce (I would put you in a high risk category of that - higher than the national average of 50%), many states and countries are starting to allow the option (and in my opinion, it may be mandatory in the future) for paternity to be established for purposes of child support.

Now a bit of information for all those self-righteous people out there:

This (the question asked) is not uncommon for women - and it is becoming more common that most of you really want to believe. In fact, think about the stat I mentioned earlier - up to 20% of what a father believes to be their own “flesh and blood” are in fact, not. Love is the worst reason on earth to get married. Shackup, live together, have tons of sex - even spend lots of time together doing “other things” - but marriage. It is a civil union between two people. There are laws (yes, laws that can be broken and have consequences) governing that union. Although, personally, I don’t believe lying is the way to go - humans lie, here’s what I found with a simple search “* We are told roughly around 200 lies per day. * On average, we lie 3 times per every 10 min of conversation, 60% have a hard time without lying at least once. Most lies are harmless white lies like "Nice haircut" or "Yeah, all is good!"” … so let’s quit jumping all over her shit, at least she’s asking a tough question, that makes the majority of people uncomfortable. Evo-psychology shows us that women traditionally “marry” or enter into long term relationship based upon “security for themselves and their offspring” - we mate, and create offspring with the “best” available source of attributes for survival for our offspring.

Debate it all day long, but women want security first and foremost, once they have that, it’s all about finding the best sperm donor for their eggs. Oh, and in this case, she’s already decided what she’s going to do - and she could probably care less about the judgments from the people that answer. High horses were made for small people.
