I'm 18, and the first time I had sex was when I was about 15 with my girlfriend, after that we had sex, when we spent the day together, about 3 or 4 times a day and were together off and on for the next 4 years.

My problem is this: I get constant erections, they are stimulated by the slightest thing, looking at a picture of an attractive girl can stimulate me. And I can have sex upwards of 4 times in a row, with less than a minute break.

I sit at home and lot and play video games a decent amount, it's not that I am unpopular, just what I choose to do. When I am sitting at my desk I'll get stimulated and masterbate. However, I can do this around 4-8 times a day if I am at my house all day. I stopped masterbating for awhile and it wasn't that difficult, I stopped for around 16 days. However I just didn't really see the benefit of not masterbating since it relivies some of my tension and... gives me pleasure.
It's weird, but while I do get stimulated extremely easy and have an erection the majority of the time I am with a girl, I can control my urges relatively easily. Half the reason I can control my urges is that because I get stimulated so easily, if I have been on a bed or something with a girl for a little bit I have already gotten an erection and have started secreting precum, this is kind of embarasing for me when a girl sees that I've... started without her...
I haven't had sex in about two years, but when I masterbate if I am really trying it can take me less than two minutes to ejaculate, if I'm not around 5-10 minutes. But right after I am done, literally 30 seconds I can become restimulated and masterbate right after. I did this one time just to test it and did it 4 times in a row... I feel that with a girl there to stimulate me more I could do more than this.

I just personally think this is weird from what I've heard and read about sex, was wondering if this is a medical problem or I am just weird, either way I don't see it as too much of a problem, doesn't really concern me that much since I don't have sex too often and don't seek to. But any explanation or advice on how to correct this would be grea :)

You just have a strong sex drive and a brief refractory period. It is not abnormal, but you are at one end of the bell-shaped curve. Try to avoid compulsive behavior.

When you start having sex regularly again, you should work on slowing down your response so that you will satisfy your partner better.
