I found this old thread and thought it has possibilities. I'd love to read moments of embarrassment from posters, sexual or otherwise. We all make mistakes, and I'm sure some would be rippers.
I go back to when I was 20, it was a long time ago now and times and attitudes have definitely changed. Back then, older generations had this ideal that girls were still saving themselves for marriage but younger girls were starting to enjoy sex a lot more, marrying as a virgin was on the way out.
My girlfriend at the time was Tina, a very pretty, sweet English girl who was 19. Virginal on the outside, but behind closed doors she loved sex. If she wasn't able to practice normal sex for one reason or another, she was more than happy to engage in oral.
Her father had a birthday, and all their friends and relatives were gathered in the living room. They all loved their "virginal" Tina, butter wouldn't melt in her mouth, but I had something between my legs that definitely did. Lack of seating meant Tina decided to sit between my legs. Everything was going well until her mother called out for Tina to help her in the kitchen.
Talk about a brain fade. Tina turns sideways to use my leg for leverage to stand up. She's on her knees facing me when for some reason she decided to plant a kiss right on my pecker. She happily stands up and wanders off to the kitchen. I'm left, looking around the room at all the surprised faces of her relatives, and then I spot her father looking at me with daggers.
To say the least, the rest of the afternoon was uncomfortable. When I finally got Tina alone I asked her why she decided to kiss my groin in front of all her relatives and father, she was horrified, she didn't even know that she'd done it. It was pure reflex. I laugh about it now, but back then it was embarrassing.
