Can you have sex in the Channel Tunnel?

Originally they used to make you get out of vehicles I think, I went through late 2020 and you had to stay in your vehicle - totally suited me in my campervan with microwave/oven, hob fridge and bed in the back. I'm sure you could blag staying in your vehicle anyway even if you're supposed to get out - I've done this in ferrys to have a kip in my own bed at the risk of drowning if the ferry goes down. Though, it's actually pretty quick before you have to drive off - no sex for me, but I'd barely finished my food when I saw the car in front drive off and had to jump into the front and drive off not wearing shoes!
