Problem...: What's with me lately?

My problem is that every time I open my PC and I get horny and so... I end up watching some sexy video that turns me on. After, I close the screen right away and clean up and then don't get online again for a while... and the next time I open my PC... I do the same thing... so my PC has become a porn machine more than a productivity machine. I should be doing other things online... But lately, I'm just horny all the time. Worst of all, I've no girlfriend. She moved out over a year ago... When I'm with someone my desires are sated with them and I don't spend time watching porn (at least not serious time)... I'd much rather have a girlfriend and an intimate relationship. Before my last girlfriend I used to spend time on the dating sites... or fetlife... trying to meet someone. But now all I want to do is get off. But it's killing me because I don't think I'll have much of a chance to meet anyone if I don't break out of this rut... I think part of the reason was/is because I've had some trouble getting over my last girlfriend. She is really pretty... and I still love her... but it's over and she's moved on and I'm trying to move on. But it seems like it's hard to muster up the desire to meet someone new. Maybe that will change over time... I'm not thinking as much about her as I used to. I really need to meet someone new. This not having any hope of actually having sex or being intimate... isn't for me. I need an intimate connection... that trust and love and intensity of knowing someone else intimately... is very important to me. Anyway..., that's a little of what I'm going through at the moment...
