Is it normal to be scared to show affection to the people you're closest to?

Well I'm never touchy-feely around my immediate family or even my other family, really. Sometimes I feel like I'm the black sheep to shy away from everybody when they're so touchy with me sometimes. It makes me want to cringe and I've tried explaining I'm not touchy-feely, but the only thing I've done is just stay away. Give hugs, kiss them, and tell them you love them but if it hurts or feels wierd, do it rarely. That's all I've done and it works usually.

I do that all the time. When I'm close to someone I create barriers shut my feelings away from them.. I think you are a affectionate person maybe your scared of oppening up? Maybe you don't want to be vunerable and let your feeling be out in the open? Maybe something in the past happened to you where it left you incapable of being able to express how you feel but you know that they know you care for them like they can read your mind so you never have to say it out in the open? Do any of these describe you? I said these because these are some of the reason I'm incapable of showing affection.

It's easy to introduce a touch instead of a hug. Just put your hand on their shoulder instead of a hug or touch their arm. A small gesture like that lets people know you care. Introduce small gestures first.
