sextathon 

A sextathon, like a marathon, but with sex, begins usually in the late afternoon and goes into the wee hours of the morning. Just when you think it will end, it doesn't , because one person just keeps going and going. A sextathon can last hours leaving the parties feeling dehydrated and a bit sore.

I am exhausted, didn't get any sleep. I started this sextathon with my BF and he just kept going , and going. Took me a few days to recover.

Sextation 

Sextation is a travel experience, such as a vacation, where the primary recreational activity happens to be engaging in sex with your significant other. It can also be used when there isn't an official vacation, but one is staying at home. Similar to a stay-cation, you don't need to leave home to enjoy the many benefits. It usually implies that the sex is extended, over a day or more, like a vacation, but a sextation.

Oh my God, my new BF is so hot! We didn't leave his house for three days - it was like a total sextation -three nights, and four days. All inclusive. I need a vacation!
