Hate being touched - is something wrong with me? A lady asked for an advice

From the time I (28F) was young, I’ve always hated being touched. I would do anything in my power to avoid saying “bye” when leaving family functions so that I wouldn’t have to hug people (and still do).

My boyfriend, and those before him, have always made me feel like something is wrong with me because I don’t like to cuddle. I have no problem with touching other people (appropriately obviously). I’m a nurse and I have my hands on people all day long. 

I have no problem rubbing my boyfriend’s back or arm/placing my hand on his leg while he drives, etc. But when he does the same to me it’s like my body subconsciously pulls away. Does anyone else experience this? Is this something I should seek therapy for?
