I was going to say something similar. There's a big difference between being fun and being just stupid.
I got turned off once by a very attractive and fit hotwife after I found out how many guys got with her in the 5 days we were talking to workout a meet up.
We all have a history and this...
Just last month I had a 23 yo chick at work that was hitting on me. We had a hot and heavy fling over the course of about 5 weeks. She swallowed for me every time.
I'm going to have to say the first time me and a couple I had been playing with pulled off a successful dvp creampie. We had been trying to time our orgasms so we could cum at the same time and we finally pulled it off in a hotel one night.
I started going raw once a long term couple I was with got pregnant with their second ....... I got a vasectomy soon after so all that messy fun continued once she was back after the pregnancy. Such fun times. It's great knowing you are safe.
I was 19 and was seduced by my biology teacher from high-school while I was doing landscaping at her house. Her and her husband apparently were swingers and we spent that entire summer fucking at her house.
It's quite a story and was a lot of firsts for me.
