I (23M) like this woman (22F) I’ve been dating a lot but she has refused any physical affection even after 5 dates

Everything is going well with her besides that, I’d be happy to be official with her based on everything else. We get along together quite well and I’ve enjoyed my time with her, but physical affection is very important to me in a relationship. She’s had only one long-term boyfriend in the past, and wants to take things slow. I agree with taking thing slow, but on our fourth date when the moment felt right she refused a kiss when I asked. I haven’t initiated since then. And it just makes me feel kind of awkward and unwanted. And we haven’t hugged after dates.

In the past when I’ve been dating, the women who were into me became quite affectionate within 2-3 dates and gave obvious signs like touching me, wanted to hold hands, kiss, make out etc.

So I’m just wondering if anyone has had this happen to them in the past and if it has worked out. Or if any women might have any insight into why she’s doing this.
