Nudity of father son/son-in-law

Being raised a nudist all my life I have seen my dad, brothers naked and it never occured to me/us to be anything else but normal.

I agree...I think it is natural in the settings you mentioned. Bravo that you all are cool with it.

Slippery slope

No, nothing strange at all. I wish I had the same kind of relationship with my father.

Being around each other naked gives a feeling of total honesty- It shows that you have nothing to hide. Even showing your erection is a sign of total honesty and freedom. People who think it´s about homosexuality and hidden desires have it all wrong.

NO!!!

nothing wrong with being naked as long as you are both comfortable with it

No. As long as it is just male bonding and being comfortable with your bodies. But if it ever gets sexual, approach with caution.

My family was not involved in the nudist lifestyle but we were brought up to be very comfortable and not embarressed with our bodies. My two younger brothers and three younger sisters as well as my parents went about our daily activities with mostly open doors. Walking to or from a shower or changing when someone walked by your open door was just the way things were and nobody thought anything about it. I will say that having to shower after gym and sports activities in junior high and high school was a non issue for me but very traumatic for some of my class mates.

i grew up nude around my dad and brother and step brothers as well as a favorite uncle, yes there were many times when i saw erect cocks as i was the youngest it always made me curious about the way men and boys were different and yet not so different, i do beleive it is ok , i have no problem with family nudeity with erect or non erect cocks .

I don't think theres anything wrong with being nude with your son or son-in-law.
Thought I've seen my dad naked quite a bit growing up, I never had a particularly close relationship with him. But my relationship with my father-in-law is opposite, we're very close. We've gone to the gym and swimming together quite a few times. We openly talk and change and shower in front of eachother, there's been quite a few involuntary erections between us, we even joke about it when it happens. The first few times that happened, I felt a little self-concious but was treated to a nice sight since he's pretty long and thick and cut with some pretty big hanging balls, where as I'm quite modestly endowed even when comparing my erection with his flaccid state. We've gotten so comfortable with eachother, we'll use the washroom in front of eachother whether we're visiting him or he's visiting us.
