Showing up nude in public where there also happens to be warm water, a nice breeze, and naked females romping around will make your son’s arousal significantly more likely.
I recommend that you simply refrain from insisting to your wife that erections do not occur at nudist sites, especially among teens, because that statement is way off the mark.
You remarked that you did not mention anything to your wife about your son’s erection in the water (” url told my wife.”) The lad is extremely likely able to sense your need for secrecy in this matter and that fact alone will make him uneasy about it, or even ashamed.
The following time he gets an erection in your presence, be casual about it. Tell him it is part of life, there’s nothing wrong with having one, he is a totally normal lad and there’s no demand to be embarassed. But do stress the necessity to behave appropriately if (when) it occurs around others, by not waving it around like a large flag and to just dismiss it if he can not readily conceal it. Not bringing others’ attention to it is the best course of action. If someone does notice, he should stay http://atnudebeach.com as if nothing is going on.
And as one poster already indicated, make sure your daughter will not make fun of him if (when) she sees him with an erection. Thirteen year old boys may be very sensitive about those opinions.
I also suggest having a talk with “the wife” and admit the information you gave her is not completely correct. She’s going to nearly surely see your son with an erection one day in the resort. She has to know he is having them, and supplying correct info regarding the issue will decrease her shock and embarassment. In case your wife understands how likely and regular erections are for a young teenage boy, she can take it in stride when it does occur and not make your son feel lousy about an uncontrollable body function.
