My cock is easily seen in just about anything I wear anyways,
Jeans, suit, swimwear, etc.
I suggest the nude beaches myself.
I have enjoyed going to the public beach though with a girlfriend from AFF ( adult friend finder) and she wears a very revealing thong bikini and I wear a male thong that barely covers my cock when flaccid.
It is white and when wet clearly showes my cock as she cut out the panel that helps hide it when wet.
She did the same and when wet you can se her trimmed bush easily and her nipples and areola's.
You can see her "landing strip" of a bush...
She loves to watch the people watching me and I like to watch the guys looking at her.
I usually hang around 7 inches when flaccid and she loves the look of my thick flaccid cock moving around and the way other women look at it.
I have even been teased and dared by her to the point of being totally erect and walk into or out of the water past a group of women or even just a single woman, as she watches their reaction's to my hard 11 inches of cock pressed and swaying and clearly able to be seen that I am erect now....
You can even see it's veins, and my head and balls, and dark blonde pubes when wet,.
She even tells me about the guys that look at it.
I do the same to her and we have even filmed peoples reactions to what they see as the other walks by.
Sometimes we go in together and pretend to be oblivious about what they can see and just ignore the looks.
when it gets to crowded we just move on...
In moments the white suits dry up and are not as see thru, But you can still see more of us then the normal suits show.
She even dared me to to do it with her in front of her own sister and mom once.
Doing it also in just our underwear and so it gets wet and you can see it All.
The look on her moms face the first time when wet and she seen the size of my cock was fantastic!
Just something we did and have done for fun.
