Growing up, I was always told that boys could come over if I leave the bedroom door open, and I see a lot with my friends that the girls would not be allowed to have boys over/in the bedroom/have the bedroom door closed or viceversa (boys with girls).
When I realized I may be gay and trans (masc), my parents were accepting and allowed me to have the door closed with girls because I was gay and still not with boys.
Then, I had a boyfriend and they said I could keep the door closed with anyone except my boyfriend.
Now, I’m nonbinary and bisexual. Would you allow your kids to close the door?
I see it as ‘This is our house but lovemaking needs to happen elsewhere. The child moves out at 18 and does whatever they want.’ Of course, the child prior to 18 needs to understand consent and the use of contraception.
