I, a 30-year-old male, believe my 25-year-old girlfriend is using me for sex.

I'm starting to feel like my girlfriend is using me for sex. I met her through a dating app. Our first date was at her home after just a few conversations online. I was a bit hesitant at first but decided to go for it. We spent about two hours chatting before taking a walk, but nothing physical happened that day. On the second day, she invited me over again. As I was about to leave, she kissed me, and we ended up making out for over two hours. She wasn't ready for sex at that point, which led to some rather uncomfortable moments for me, ha! This pattern continued for a while until we finally had sex, and since then, there's been no going back. The sex is fantastic, but we’re not technically in a relationship. She claims she's not ready for one, and our texting is pretty minimal. We usually meet about once or twice a week, mostly at her place, where we have sex. A couple of times I stayed overnight, and she joked that I could wake her up for more whenever. She often keeps going until I can't anymore. While I'd like to develop a proper relationship with her, she insists she doesn’t want any emotional commitment. She says we can be friends, but then she seems to get aroused easily. She asks me for help with small favors, which I always agree to. Last time, I was clear that I want either a real relationship or nothing at all, but she just said she needs time. I’ve come to think she’s not really into me, so why is she always willing to have sex? Over the past six months, we’ve mostly just been at her place, and she never makes plans to go out. I’m torn between staying friends and continuing our sexual relationship in the hope that she might eventually develop feelings for me. On one hand, I'm enjoying great consensual sex without complications, which is a dream for many guys. Plus, she’s really nice and educated. What do you think I should do?
