My parents would never open my mail but they get seriously pissed when I don't tell them what I get, to the point where they tell me it's their house and I'm not allowed secrets. My first big order, I planned it while they were out of town. That worked out perfect. The next order was smaller and I figured I could make something up if I had to. Turns out, mom was napping when it arrived, half an hour before dad came home from work. So I sneaked that one in, too. That was lucky

As for your father not respecting your privacy to the point of opening your things and searching your room? Maybe you should tell him exactly what it is and then turn it around on him for butting into your sex life. Scare him away with sex toys, lol.

If that doesn't work, find where he keeps his porn and brandish it at him to demonstrate his hypocrisy less

I've seen you post it a few times but I'm not sure what ibs is. I'll have to look it up. I wish you the best of luck with ibs and the nosy daddy. Maybe your Mom could get the package and talk to your Dad too. Definitely get a locking cabinet for your stuff to keep Daddy outta it. less

If you've order this stuff to arrive at your home, and he's seen the unopened box but you've successfully gotten it behind a locked door, hide all the contents (and the packing slip!) and then leave the box in plain sight, full of the most boring looking thing you have available. For example, I order a lot of books on amazon, so I would use those. Do this every time a box comes, and hopefully he'll lose interest.

Neither logic nor the law will work on nosy family members. less

That really is a very very very good idea, wont work for me but I think this could work for others.

You really need to tell your dad to stay out of your room. He is boredline creepy going through his daughters stuff, I wont disrespect him by saying anything more, as much as we all get annoyed with our parents we dont like others talking about them, so I wont. less
