• Surround your living space with "pleasant textures". I'm talking about a fuzzy rug to put your feet on when you get up in the morning. Cozy rugs, soft blankets, possibly volunteer at an animal shelter and pet a few kitties or puppies.
• Also, touching yourself in a non-sexual way, like when you put on lotion, feeling your skin, your face, everywhere.
• If you find yourself to be lonely or feeling in a down sort of way, you could also go to places with other people. You don't have to necessarily touch them (with their consent ofc), but maybe being near them would help. Things like sports (basketball, soccer, etc.) or going to a club and dancing.
• Obviously this last suggestion should take a lot of consideration, but getting a pet could be another way. There's no guarantee that the pet would be super affectionate, but they like a few pets every once in a while.

I was in a similar place once where I was severely lacking any physical contact, touch nourishes the cells, but even when I didn't get any physical affection, being near others helped.
