Open Relationship?

My boyfriend is going back to school. He is 27 and I'm 22. I graduated college with a B.S. degree when I was 20.

We have been together 8 months now.

He found me when I was on a self destructive path and helped pull me off of it.

Anyways. We have been living together since day 1 of our relationship.

To get his sports scholarship at school he has to live on campus.

The school is strict and I'm not allowed in the dorms. I live in an apartment owned by my mom and step dad and I'm not allowed to have guys over at all.

Before sex was easy to have. Now we haven't even tried.

So today he mentions trying an opening our relationship up because, "I realize that you have needs"

I hate the idea of an open relationship.

I have tried it before. I slept with a lot of other people and always told my then partner, but he lied to me once. I'm no longer with him.

I'm scared that I'm going to lose my guy.

Thoughts anyone? I know I'm emotional and I'm going to have a hard time seeing outside of the box. Any insight? Experience? Ask me questions.
