Do you really think you could allow it to happen under your own roof? Nice to think and hope it is going to happen in a safe place and not the back seat of a car somewhere. Valid point about safety. I don't think I could stand by while my daughter was having sex under my own roof, especially just for sexual experimentation sake.
Yes, I do. My parents let it happen under theirs and my older brother and I did bring our boyfriends and girlfriends home and have sex, although my brother and I were not 12 or 15 years old when we did it. I would make sure it didn't happen when they are that young and if I didn't know who the boy was, but there is plenty of space in our house for privacy and I don't think it is very likely that they would be raped when we are also home. I would probably let it happen at 16, maybe 15, but I would have to know the boy very well. When they entered puberty, I left a bottle of astroglide in their medicine cabinet and their bathroom has a bidet, so sex is pretty out in the open with them. My husband and I were very sexually permissive, but they had to show responsibility in all phases of family life. The truth is, I would rather they masturbate and play with toys, preferably alone, than have sex at this age.
Also, I have posted elsewhere about our daughters knowing full well what BDSM is, seeing our cache of equipment and having a long family discussion about it, and having exhaustive discussions about sex, S&M, relationships and taking care of one's self. I also posted elsewhere about the older daughter once walking in on us when we were in the middle of a scene, my husband and myself practically naked and me, flogging my husband (her father) who was bound and wearing a leather hood in the music room with lots of equipment strewn about the room. The 15 year old was supposed to be at a friend's house for the night, but she came home early, dropped off by an older girl friend of hers who could drive because there was cocaine at the party. If she was responsible enough to do that, she is responsible enough to have safe sex in my house.
There are plenty of times we don't even know who is home unless we call out to each other or get a phone call from the girls telling where they went after school with friends or some after-school extra-curricular activity. We all do keep in touch and the girls are extremely responsible, so it isn't like we don't know where our children are. Everybody has a phone, which today has become a semi-necessity even though we did just fine without them growing up. I trust our children and they know where they are supposed to be at given times. They do all their school work and are very bright (they got good genes for that from both of us, especially my husband who is a real brain 😎 ) and they won't let themselves be taken advantage of, especially the 12 year old who is a bit of a control freak, has a bigger mouth than I do and is not at all afraid to express herself.
If I was aware they were having sex (at a reasonable age) in my house, I would do the same thing as when they each told me they masturbate and to quote my 12 year old, "know what it feels like to be a woman," I SMILED when she said that..
