I suffer quite severely from PTSD which makes me very nervous when it comes to any sort of physical contact. Would love to try and find someone who i could trust to become a regular cuddle partner
Welcome, @AlexW1997. You are not alone. Practically everybody on Cuddle Comfort has some kind of story to tell.
There is some good advice in this thread: https://www.cuddlecomfort.com/forum/discussion/10731/how-i-found-happiness-on-cuddle-comfort#top
Given your history, I suggest that you consider a professional cuddler to get you started. There are a number in London who have experience of this kind of thing, and are very caring people. They will go at your pace. Look for those who have lots of Karma. They are not trained psychotherapists but they will look after you.
