I want to become a nun because I feel like no guy will ever want me?

Let me just say I love God. God is important in my life. I am not trying to be disrespectful to God at all. I'm just lost and not sure what to do.

A few years ago I was dating this guy. I wasn't religious at all back then. My mom and older brother motivated me to do stuff with my ex. Not full blown sex but just oral hands.

So I'm not a virgin anymore. Now years later I found God and I am extremely deeply regretful for what I have done. I want to wait until marriage but how can I find a guy who'll wait/respect me if I am not a virgin. I feel like I don't deserve anything and I'm am just a slut so I should just become a nun.
