Happened 10 minutes ago. My girlfriend and I are in a hotel for the night and she wanted to invite some people over for group sex. So I made a reddit post looking for people. I copy pasted this to a couple subreddits for maximum results.

My friend just had a newborn and I happily took some photos with my DSLR. She asked to see the photos and the best way for me to get them to her while I'm in this hotel is to copy paste a link from Lightroom to her. So I got the link, paste it in the text, send it. I quickly see my reddit post in our text conversation reading "Girlfriend and I are looking for a F or MF to come back to our hotel they we got for the night. It's her birthday so we wanna have some fun tonight. Pics of us are on mine and her profile u/agaribay1010" She just tells me, "that link didn't work..."

TL;DR: I accidentally let my friend in on my sexlife leading to horrible embarrassment for me
