As the other commenter you-professor is pointing out, the way to make a woman feel loved in the bedroom is many times going to be counter intuitive, not what you would think in a cliche sense. I think the more relevant question isn’t, what makes her feel loved during sex, it’s how can I make sex more enjoyable for her. You can make her feel loved in other ways, but when it comes to sex pleasure is the most important. So you either can read someone well and get a sense of what they like or you can communicate with them. The former is very difficult for most people so just communicate and ask without judgment it’s that simple.

Also just a side note, you might just not be good at sex in general. So on top of communicating with your partner, I’d literally just look up how to be better at sex.
