1. Girls usually don't make a big deal about sleeping with/dating virgins..it's not something all that special.
2. A) work on your self esteem. You should not be seeing your partner as "you're not going to get anyone else/better than them". When girls do that, it usually ends up in an abusive relationship. B) Guys who want to cheat will find a way. And C) it's usually the norm to expect partners to love you enough to not cheat in the first place. It might be different in other countries.
3. Again work on your self esteem. You should not be settling for something because you think you can't do better. This one gives off "nice guy" vibes.
4. See number 2 and 3.
5. You have your own confidence issues and I don't care if my future daughter sleeps around as long as she's safe and happy. Since this is off an incel website, I think you're just going to teach them your bullshit.
So no.
