I'm not one that really needs regular "cuddling". I do love being hugged up to my partner and chatting and all, but it's not something I need often. I guess we do have a decent amount of physical touch, if not more than normal. Lol. We don't cuddle often and I don't find myself longing for cuddling. It's very rare for me. I guess I prefer other types of contact than the cuddling part.
I certainly wouldn't stray though. Ask your partner for more physical touch when you're around each other or get a pet, if you love pets. If not, it wouldn't be the best idea because they need lots of attention too.
I have 3 cats, a weiner dog and hamster. Of course Hubert hamster doesn't sleep with me, but one of my cats and sometimes 2 sleep with me on cold nights. My weiner dog is my sidekick. He sleeps with me every single night. He even waits on me outside the bathroom door. Lol. So if I did ever get the urge to cuddle, they could be helpful to snuggle up to. I think it'd help a great deal.
