am I over reacting?

Hi,

I need some advice. This is my first time here. I don't know where else to turn. I'm too embarrassed to discuss this with my friends because they all know my boyfriend.

Last night I woke up to him using my hands to spank the monkey himself while I was sleeping!!! I was mortified! I was disgusted. I felt betrayed. I screamed at him and cried and threw him out.

He is normally wonderful. We knew each other for two years before we even began dating. He's never done anything like this before. We are pretty much living together and have been together for 5 months. He's always very sexual and I have a hard time keeping up with his libido. He wants sex everyday, 3 times a day if I could! But my health isn't great (I have severe migraines) and I take loads of medication. We have sex many times a week. Sometimes I get frisky and go 3 times a day on the weekend. And I know he loves me deeply. We've mentioned marriage down the road.

But last night I told him I was too tired. I had a migraine yesterday and those take alot out of me. He seemed disappointed but alright with it. And then THIS happened. I feel like I lost my ability to trust him.

How does someone think it's alright to use any part or your body to get HIMSELF off while YOU'RE sleeping!!?? Am I crazy or was that just horrible?

Do I forgive him?
Help.
I love him. But I'm just ....speechless.
