Hi, i have two 'first' experiences....
The first is at the beach with my girlfriend. Our very first time at Morfa. We got there and walked the long long walk to the naturist area. I was nervous because i didn't know how she would react. I needn't have worried on that score because she stripped off before me. I remember taking off my underwear and standing there totally naked expecting some sort of response from someone. No one batted an eye lid, so from that moment i felt relaxed, and had a wonderfully restful afternoon.
My other 'first' was my first ever home visit from another naturist. I had been chatting online with a guy for months and arranged for a meet. As i am always naked at home, i answered the door like that (i had checked to make sure it was him and not a neighbour lol). He came in and stripped off almost straight away. We chatted over coffee, and had a very nice few hours.
