Cuddle on the sofa - no, there's usually at least one cat between us.
Hold hands - not really, haven't been out anywhere that provides the opportunity for 18 months and it interferes with the Fitbits' tracking
Snuggle up together in bed - rarely. There's usually one cat between us and another hogging the gap between the pillows, smirking because he's been so clever in identifying the opportunity and getting away with it. It would have to be about 3C before we even consider getting close at night outside anything sexual.
But, on the other hand, I had to wake him up this morning because I had an early morning blood test and managed to forget my door key, he came down to let me in, put the kettle on for coffee damn these fasted tests and gave me a hug and a kiss before plodding back upstairs to go back to sleep.
He also fake tanned my legs last night, regularly does sports type massages after the gym, will bearhug me at least 3 times a day to crack my ribs back into position (I have hypermobility and the facet joints hurt when they shift) and will help me with putting on emollient/steroid creams for Psoriasis and taking off my gym compression tops and socks when I'm too knackered afterwards to move. I will usually touch him when walking through the kitchen and only have to sit down on the rug in front of him when he's watching TV to get an automatic neck and shoulder massage.
We spend a lot of time doing our own thing even when in the house together, so it could be 6 hours in different rooms of the house before we even speak.
It's a different type of intimacy, rather than just 'affection'. It's easy, it's comfortable and frankly, more rewarding and useful than squishing up together on a too-small sofa.
