<human>: Give me the gist of the text in a nutshell

The other day there was this show on tv that had nudists, I was flipping through channels with my girlfriend and we had a quick laugh at it.  I thought it was a good moment to bring up the subject, so I asked her what she thought of that.  She said she thought they were kinda weird and she'd never understand it, but that's pretty much all she said. She sounded kinda disapproving, but more in a weird rather than gross way.

The thing is, I grew up in a nudist family; including me, my parents, and 3 sisters had this house in the country and we would participate with other nudist families.  There were other kids my age, old people, middle aged people.  Normally at the beach or at the park or wherever.  Growing up, it wasn't anything abnormal for me although I realised at an early age most people aren't like that.  I don't see nudity as always non-sexual, it just depends on the contest.  I don't see a naked family at a nudist beach sexual at all, but for example when I see my girlfriend naked in the bedroom, that is sexual for me.

My parents are still nudists at home and I really don't have a problem with it. They wear robes or clothes when guests arrive though.  Ever since moving out of home I'm no longer a nudist although I do like to lounge about in my underwear from time to time and my girlfriend has no problem with that.

Am I obligated to tell her about my family's nudism? I guess she'll find out eventually right? I grew up a nudist, and I'm not sure if that's a relevant part of my past that she should know, I don't want her to think I'm weird if she finds out later unexpectedly or anything.  She hasn't met my parents yet, but she will soon, and they will be wearing clothes.
<bot>: Grew up in a nudist family.  Girlfriend doesn't know about that but might think its weird, should I tell her about my past?
