I don't care if people find something out, so I don't hide things, but I also don't think it's everyone's business or that they even care. So, while I enjoy the plain wrapped boxes, I don't care if the postal carrier figures it out or the TSA finds my 'weapon of terror' in my carry on.
That said, I also don't enjoy making others uncomfortable on purpose. So, for instance, I don't leave my sex toys out if I have people over. But I'm not hiding it because I care if they find something out about my sexuality. I just think it careless to give them more info than they're comfortable handling. But, my sister or close friends will get the tour if they like.
I've always been really comfortable talking about sex or other personal issues with people. I'm curious & I guess it makes me feel closer to someone, like I am seeing into the real person. And maybe because they sense this, even strangers tell me the most personal things, (but I'm not sure why).
I also have never been squeamish about seeing my parents kiss or been bothered by the idea of them having sex. Having them walk in on me masturbating when much younger would have been upsetting, but not the knowledge that it's something in which I indulge. If it happened now, I'd just ask them to give me minute & that would be the end of it. (...that's assuming they didn't walk in on something such as auto erotic asphyxia, then I might expect some questions or a raised eyebrow!)
All this is easy for me to say, though because I haven't participated in anything that most of the puritans in the US consider all that scandalous. If I had a fringe type fetish, or my livelihood depended on keeping it quiet, perhaps I would.
