Insecure I’m a virgin while engaged?

I am a true believer of only having sex once I am married. I full around w my fiancé but never have full on sex. We are long distance and sometimes overthink things. He is very honest and loyal but I get insecure because men have needs? He does all the right things and is super patient with me. It’s just that it’s hard to not overthink while being so far away from someone. I guess I just need to work on myself and my insecurities. I have a lot to offer and am worth a lot.
