I welcome other people to be naked, hard/horny around me, and if I'm hard, I welcome others to feel and taste my erection.
I have had a number of occasions to admire others erections on the beach. Strangely, when I was younger it would bother me if a guy would be aroused looking at my naked partner and I laying in the sun. That all seemed to change at about 40 where I started to really enjoy when other men would get obviously aroused at the sight of us and I even started to encourage it by teasingly playing with my partner while they watched. There are still some people that just give off a creepy vide but 99% are just enjoying themselves and we feel we are in-tune with their vibe and enjoy the day together aroused. My last two partners have been very accommodating in these games as well. A fantastic way to waste a day. I love when another couple engages with us as it appears to be equally exciting for the women as well.
