I had last week an 22 yo UK girl via c ouch s urfing staying for one night.
As you could read earlier, I live a naturist life style and my guests also try it out (till now all but one without any issue).
So she tried the naturist life style, of which she wrote: "it felt weird for 30 seconds only"
We chatted a nice evening.
I don't remember how we got the topic of doing outside dares, but she was in for some, it was late enough (1AM or so) so we did the following:
2 nude pictures of her in front of 2 different well known monuments in my city
a naked run of both of us to a statue to take some selfies, the statue is in the middle of a 2 x 2 road, it was calm of course given the time of the night but we had to hide though for a passing car, which was thrilling fun!
she called a weird but wonderful experience, and is planning to come back

unfortunaly the pictures are on her smartphone, I asked a copy but not sure I will get them
