Hello newcomer! Dont jnow where you live or what the social mores are around teens and dating but...If you're good with your son being sexually active then your home is arguably a safer place for that activity than, say, a car or something. Probably a good idea, though, to have a talk about safe sex, consent etc.
If you're asking for a completely different reason my apologies.
I use my Deck when I travel ( which is all the time). I bust that thing out on the plane, on public transit and in my hotel room. I literally do not care what people think of me by doing so.
