Casual sex?

I just had casual sex for the first time in a long time. It was so plain. I mean I know that’s how it’s supposed to be but like it was so bad. Maybe I’m just bad at it? I’m not sure but is it supposed to feel like that? I’m not sure it’s been such a long time. The last time I had sex was in February and it was extremely intimate. So much feelings. It was so great. Ugh I’m not even sure I want to ever have casual sex anymore. Any tips on making it more exciting or so I won’t be so bad at it? 😣😣 also, the guy hasn’t texted me so I’m assuming that means that he thinks it was shit too? Idk 🤦🏽‍♀️
