What is going on with me?

I'm 18M and recently watched a video on YouTube about people having blind dates, they got 3 pairs of a man and woman, and put them in a box that was just big enough to have some space for each other, the challenge also was to be in there for 12 hours and ask each other some questions, sometimes provided by the host. Anyways, 1 of the 3 couples really seemed to have a great connection and they ended up kissing each other and cuddling etc. (on video) , and they ended up as a couple but to get to my point, a day after watching the video I was thinking about it again and how cuddling or hugging or hooking up would kinda feel weird to me, like I didn't get many hugs growing up or had that kinda connection with my family, and if I did later end up getting some It always felt super awkward and uncomfortable to me (even from my father, mother...) so that got me into thinking how I would feel about cuddling with someone even If I might have a great connection with them, would I still feel as weird about it, or not at all? (Obviously you guys won't now but I just wanted to share my feelings about it and talk) like it's almost like kissing I might be able to do didn't actually do but hugging or cuddling probably would feel awkward and uncomfortable to me, it also get me into thinking if I could even ever randomly hookup with someone I find attractive , like I do watch porn occasionally so I know I'm attracted to strangers basically but actually physically then doing something like that casually (not in terms of relationship, since it probably wouldn't feel that strange) I don't really know if I could do that.

Like I hope it might not be causing problems in a relationship on my end, like will I ever be able to get over this or how can I work on it?

Any advice is helpful, so thanks beforehand!
