On a number of occasions, but one of the most memorable was when visiting my grandparents over the weekend, when I was 15. Casual nudity, for fun or relaxation, wasn't done, but domestic nudity, for hygiene, work, after chores cleanup, haircut, health related inspections and checkups, were among the few examples of me having too strip too my birthday suit. Getting measurements and adjustments for clothes was one of the most invasive, because the whole process involved special attention to the body and it's contours, configurations, and other private details, including habits and phases. Like what activities I would be prone too get myself involved with, or changes in the body that required a certain degree of discretion in public, and the room in my pants and breifs too maintain that level of descretion, let's say, in the classroom when an unwanted erection takes place. Anyway, that level of descretion in public, meant zero room for descretion, or argument, when Ms. Dec ries dropped by with clothes her son had outgrown that she wanted me too try on. Grandma was thrilled, and welcomed her opinion and insights on how too go about anticipating my rate of growth and development based on her own son's advance through puberty while wearing these clothes. I didn't exactly know what that meant until I finished trying on the shirts with them checking the fit and finish in the shoulders, tummy, torso, and arms. Next, the briefs and then the pants. When I picked up the underwear too go too the bathroom to change, Grandma scolded me for waisting her dear friend's time by walking back and forth through the house, between the bathroom and living room, on opposite ends of the house, that would deny them the opportunity too take measurements and gauge fit and room for expansion. I was going to have to try them on right there, having each and every undergarment fitted for size and shape. After initial measurements of inseam and girth, of course. Being a close family friend, who apparently had even changed my diapers a few times when I was an infant, meant I was out of line for being shy about grandma removing my clothes in front of her, with my resistance too grandma trying too lower my underwear in front of her, resulting in my going over grandma's knees for a bare bottom spanking, with my penis and testicles dangling between my legs in front of Ms. Devries. The ship had pretty much sailed on on modesty being invalidated, as it had become non-existent as far as I was concerned. I cooperated with grandma finishing the removal of my briefs from my ankles, having too apologize too our close family friend I had no memory of with a partial erection forming before her eyes. Having my genitals lifting, moved too this side, and that side, as I was instructed too hold the end of the measuring tape, while they were handling, moving, measuring, and discussing my anatomical dimensions and configurations, and how those numbers and predictions of future growth translated into form fitting clothes that looked decent for public participation. This left no part of my midsection unmeasured, u handled, and unfocused too their attention and discussion. It's kinda disconcerting having your boyparts handled and talked about in the third person, as though I wasn't even there too hear and understand, just my genitals, their expansion from being touched and held by for taking measurements, discussing growth through puberty and room for saluting, as they colorfully made reference too my erecting penis and tightening testicles, which got measurements in length, girth, and volume needed to occupy inside my new hand me down underwear, so they would know what to since, let out, or put aside for someone else too try on. Before trying on the first pair, grandma shot the rest of my male dignity too hell by having me bend over and spreading my buttcheecks wide apart so they could check my hygiene and not risk skid marks or otherwise soiling of those nice, clean undergarments. If I couldn't beat em, join them, I said too myself as I thanked Ms.Devries and Grandma for their compliments on my exceptional hygiene in the summer heat, with my scrotal sack stretched by Ms. Devries fingers pulling it towards her face for a closer look, Grandma shining a light on my anus and penis as she moved my fully erected penis from side too side, up and down, and into the hole of my eurethra, being exceedingly thorough as a cationary lesson on the penalties of disrespect towards my elders. My erection irritated Grandma as another inconvenience too getting finished with this task, but Mr. Devries pointed out she had the same issue with her older son at the department store fitting room trying on some new briefs for him, the store having an open packed policy on such items for customer convenience. She used the same solution on me, putting on a pair of briefs, holding forward the waistband with one hand while reaching into the fly hole in front too thread my dick through the opening, then my balls, with me struggling too keep a straight face and pretend indifference, which didn't fool anyone. It was actually more embarrassing having my junk protruding from the opening, than it was having them removed, making me feel less exposed, being completely naked, than I did with them on. It only goes downhill from there, but we were grateful for the new clothes, me less grateful for the reality check they gave me in reminding me that male modesty is a hoax perpetuated by the Feminist movement and privacy is an entitlement males do not posses in the real world.
