How sex affects us

After being single for a little over three years I finally decided to give it a try. I first started dating Mark, went out with him about three or four time. Mark is a free spirited Pisces, so mellow and romantic, would sing to me (he is a singer and actor/model). Sweet as they come, could read me like an open book, which I found great, there was no need to explain anything, what I was thinking, what I was feeling, just by looking at me he knew. Mark wanted certain "things" that I'm just not into. We are still good friends but knew we were at different places in our lives. Around that same time I met Michael. I would love chatting with him and missed not talking to him when I didn't see him for a while. But I should have known....Getting involved with someone you work with is never a good thing to do.
Michael is a wonderful soul, with so much potential. It hurt to see that he still doesn't realize all that he is capable of achieving. I know when the time is right he will. I deeply care for Michael, but being intimate with him only left me drained.
For so long I stay celibate, in full conviction that it was the best thing for me. Conserving my precious energies is what I had done all along, I felt so charged.

It's been almost a week since Michael and I ended things after coming to the conclusion that it would be the best thing for both of us. I currently feel so psychically depleted and even though I am working my way back to where I was before I hate to think that I will never be able to share my life with anyone.

Can any one relate to this?
