This one made me laugh. It feels like bragging, but I'll share.
I was a teen mom, I got pregnant at 18 so yes, when he was 15 I was 33/34 and, without bragging too much, I looked good. I think I had the best figure I had ever had in my thirties, I was too skinny in my teens and twenties so in my thirties I had just enough to have some curves without them sagging. Yes his friends thought I was hot, how did I know? I used to hear them teasing him about it. How did it make me feel? Flattered? A little uncomfortable maybe - not in a bad way, just cognizant for me to not do anything to lead them on or anything like that.
One of them was more aggressive about it than the others. "Oh Mrs ******* you look great in those shorts." and stuff like that. We had a pool and the kids would hang out at our house in the summer. If I knew the boys were having friends over I'd either not be in the pool, or if I was going to be would wear a tankini (That's a 2 piece swimsuit with a top that comes all the way to the bottoms so it covers like a 1 piece. I hate 1 piece swimsuits because they're miserable if you have to go to the bathroom - you need to pull down a bunch of wet lycra and then pull it up again and it's cold. yech) but sometimes I wouldn't know they were coming and would be in a bikini.
One time when I was virtually certain I was NOT going to have a bunch of kids over, I was wearing a new bikini I had bought for a trip we were about to take - I was trying to tan with the suit I was planning on wearing so I wouldn't have weird tanlines on vacation - and the kids came back. Their plans had changed or something, I don't remember. While the suit wasn't particularly revealing, it was more so than I would usually wear when my kids friends were over and this one particular boy couldn't keep his eyes off me - to the point where I went into the house. Later, when he was changing out of his swimsuit he made sure I'd see him naked (I was doing laundry and our laundry room was right next to the downstairs bath and he opened the door as I was walking by). I got an eyeful. I think I said something like 'Oh, sorry' and turned around.
The funny thing is several years later, this kid became a male stripper. My son was home from college and they were all hanging out etc and he mentioned he was dancing and where (he later slipped me a business card lol). No I did NOT go see him, wasn't even tempted.
So how did I feel? A mix of feelings in about this order: Amused, Flattered, Embarrassed, and maybe a little Proud?
