I'm finding this thread confusing with all the deleted posts!
Why do some of you with older DCs want to pretend you're not having sex with your partner? I have never understood this discomfort with teenagers knowing that their parents are having sex. We would much rather our teenage DCs grew up having a full expectation that when they have also been married as long as we have, they will be having sex too.
When the time comes, we will also welcome BFs and GFs to stay overnight. Just because we can't see it or hear it, doesn't mean it's not happening, surely? If people want to have sex, they will find a way. For teenagers with no means of funding hotel rooms, that usually means the family home, whether their parents approve of it or not. If it's the latter, they will usually do it when the parents are going to be out of the house.
If that's not possible, the alternative is a cramped vehicle or al fresco. Having to sneak around encourages a thought process that sex is an illicit pleasure and something to hide and I just don't understand why people are so puritanical about it.
Some of my friends' parents took the view that all this discouragement would mean that sex wouldn't be on the agenda till university - and they were more or less right. However, when those friends were let off the leash at university, some of them became unhappily promiscuous. In later years, they've told me that because their parents always put such a premium on sex as sacred and to be "saved", they confused it with love and spent their university years as miserable as hell, when they should have been having the time of their lives.
I think because my parents were broader minded than most - and encouraged an adult dialogue, I never felt the need to sneak around and consequently enjoyed my teenage years and university afterwards. I've also never had any hang-ups about sex either. I was also very mindful that my mum married young because in those days, it was the only means of having legitimate sex. The marriage was a disaster.
It is far better IMO to educate DCs about treating sexual partners with kindness, fairness and decency, making sure that there are absolutely no double standards within the sexes. That involves taking full responsibility for contraception. If they are having sex, it's not regarded as something that should be hidden, rushed and uncomfortable! If they are sleeping in the family home overnight, that responsibility extends to other areas too - making and changing the beds, not leaving used condoms lying around, being discreet if anything causes discomfort - the actions of any responsible adult in fact.
I think all of this will prevent our DCs wanting to rush into a live-in relationship, marriage and DCs too early.
