Think the weirdest things would be...
One night during the summer, my fiancee and I decided to take a sleeping bag and go have sex outside, then snuggle together and look at the stars. (Live in the country, but the highway is at the end of our driveway) So we went out, was very romantic and thrilling having sex outside at night. Then some HUGE transport truck drives by, rumbling and growling really loud, and we got scared because we didn't know what it was at first. He got unhard

and we got cold so we went and finished inside and did it another night!
Another weird thing...when we were first together, we had to sleep in the same room as my mom (her bedroom is the living room) and we were fooling around one day during a movie, while she was in the kitchen...and I was giving him head...he was about to cum and she came in the room, but he was so close he came in his hand. She sat down and started watching the movie with us, so I had to distract her long enough for him to get up and race to the bathroom and clean up.
We also had sex one night while she was sleeping, and I accidentally let out a moan which woke her...she asked if I needed some pain killers for my back (I have back problems) because she thought it was a moan of pain haha.
