Some people don’t like being touched, especially when you are on a first date. Take it slow or your relationship might end before it starts.
Cracking a joke that’s just inappropriate enough to make her slap you on the arm, but appropriate enough to make her laugh at the same time will trick her into touching you. However, these kinds of remarks are high-risk and can get you in hot water among people who are sensitive. Try this at your own risk.
If you are not dating you could touch her on the arm or hand when she says something funny, if she responds well, you may be able to touch her on the leg or possibly hold her hand after a while
