I honestly don't know anything about this. But I noticed you had yet to receive replies to this post. So I thought I would write one. (Hopefully you will yet hear from members who have actual experience related to your concern.)

I'm old enough that I'm well past the point where these sorts of concerns are of significance for me. However just as a general observation my thinking would be that, when it comes to touch, it's best to let the woman take the lead along with being open about one's insecurities surrounding touch as well as other aspects of dating. Communication is the bedrock of any successful romantic relationship. And so the sooner good communications are established the better it seems to me. At least these are my thoughts with regard to your post.
