I think its all depend on habbit..
my hubby didn't like hold hand, hug and kisses in the past...he feel very uncomfortable especially when we are outside.. but then I slowly teach him and tell him there nothing wrong to do that..
he never actively hold my hand or hug me in the past but now he will give me a kiss first when we meet after work..
so I think u just need to be patient and let him know that u like hold hand and etc...
then he will do it naturally...
