Need some advice for my situation as I have this fear now

So I am M 21 and I got out of my first relationship some time ago. Now my ex had a lot more experience than me and she was very deeply connected to the ex before me.

Through the relationship, I tried my best as I was a clean slate and I gave my whole loyalty, efforts, love, time, etc to her and in the end we ended up breaking up due to the future complexities and she still ended up keeping me as a friend while also remaining to stay connected to that ex when were friends (not when we were together).

Now while she did all that, it was fair to say as I have realized that she really did just end up taking my first time in a relationship and treating it like trash due to her still missing her ex and all. After this, it has made me question that even after my efforts, how this still happened.

Now while she did do that with my emotional experience, we did not ever have sex and due to that I’m still virgin while she had experience. Now while that ex is gone now, I’ve recently developed this fear that for my next relationship, what if I get my sexual first time taken and thrown as trash too just like she did with my emotional one.

This fear really does make me anxious over my future partner comparing me to past exes because I know that there are a lot of chances a girl around my age will have had experience even if it’s little and not be in my situation (I’m not looking for only virgins like me, I’m open to all) but again my fear runs in that I don’t wanna be used as trash for this experience.

Also when I think about this, it’s that while people who break up may still remember their exes sexual habits or things they liked etc, I fear that while I bring a clean slate with no acquired bad habits, my future partner can just come and continue to use their bad habits from the past which they acquired and use those with me because i don’t have any experience.

So yeah any advice to me in this situation and maybe help me look at my fear and get over it.

Thanks for the long read lol :)
