I dont enjoy sex with my boyfriend

I am dating the nicest, sweetest soul.

He is everything I have ever wanted in a man.

The only issue is I dont really feel satisfied sexually. And sex isn't everything and I don't think it should be a deal breaker. It could very easily be me. I'm not trying to blame him. I just dont really love the sex. I love him. I dont love the sex.

Sometimes it feels just rough and not smooth and our rhythm has always been "off key".

I am loyal and faithful to him 1000%. I want to be with him forever. I would love to marry him.

What should I do? How do I talk about this without being a terrible person???
