<human>: I've been with my girlfriend for nearly a year now, everything is fine, she's brilliant. I really love her however this part of her lifestyle really makes me uncomfortable, and it's not that I haven't tried.

Her family are nudist (or naturist, as some call it). Her parents met while they were at some events related to this, and they raised their family (my girlfriend and her two brothers) in this lifestyle. This isn't my girlfriend deciding to go nudist out of the blue, she's always been like this.

And I've met her family multiple times, they're all very nice and decent people. They respect boundaries, when I am around they all wear clothes out of respect but obviously when they're with themselves or with other nudists they're nude. I don't attend those events but sometimes see pictures and videos, and the whole idea of my girlfriend attending such events makes me uncomfortable to say the least. I obviously don't see anything morally wrong with nudism, it's just different lifestyle that I'm not comfortable with.

My girlfriend knows my overall feelings that I don't find this really that interesting or something that I would be comfortable with doing myself, but haven't told her of my troubles dealing with her doing it as I don't want to seem controlling or criticising her rather innocuous lifestyle. Just the other day she was at this party with their family friends and I saw some pictures, the whole thing made me really at unease and uncomfortable. It would have been one thing if this was only her family but it's not, she doesn't mind people taking nude photos at these events or anyone being there, not at all. 

Am I too old fashioned and close-minded? I don't know. I know this is an important of part of her identity and she enjoys this lifestyle and I want her to be happy, but I've tried to feel rather indifferent towards it for nearly a year and still have trouble dealing with it.

Suggestions?

<bot>: My girlfriend is a nudist which makes me rather uncomfortable. The idea of her being nude with people I (or her) don't know isn't something I can be comfortable with. Am I wrong to feel that way?
