OP just keep having sex with her and keep your eyes open for a girl who will give you the love and affection you want.
Don't listen to the first part of >>112974 's advice OP. This whole "don't tell a woman first that you love her" is BS. This is a PUA r/TheRedPill type of mentality. Drop it. You said your piece. She doesn't want a relationship. So keep fucking her. Go find a woman who does want a relationship. And then jump ship when you do and move on.
I've been in a 10 month on-and-off relationship and recently been in a 4 month relationship. The first girl told me that she loved me first. The second, I told her first. The second girl dumped me because I was a douchebag. Not because I was a "beta" or a "nice guy". If a man is sexually attracted to you, being a sweet romantic guy is a plus. Just don't be clingy. When I was a sexually inexperienced guy, I was clingy/needy as fuck. But after I started getting laid, I cooled down and became too aloof if anything. My last two girlfriends complained that I don't text them enough. Hence the whole me being a douchebag thing.

If pantsu is going to start laying down the banhammer on non-virgins and posters with friends, this board is going to degenerate into wizardchan. Wizardchan is absolutely terrible.
The internet is absolutely fucking terrible for seeking relationship advice to begin with though. ESPECIALLY 8chan or 4chan. This is an incel board. How are you supposed to figure out how to navigate relationships asking a bunch of virgins and sexually inexperienced guys? Reddit is fucking terrible too. I have seen some positive advice on Reddit. But the vast majority of people on Reddit are idiots.
If you want relationship advice, the best way to go about it is to find people who are in successful long-term relationships and ask them for advice.
