So I haven't been around much. But these forums provide an invaluable resource as far as sex questions go. I don't know where else I'd ask things. Anyway!!

My legs will shiver when I start feeling really good during sex. Or when I get kissed just right.

And when I'm up on top, as I get closer to an orgasm, my legs and hips will just shake uncontrollably and when I actually do come, I see swirling rainbows like oil on top of water and my whole body will shake even harder. Almost violently. I do retain a small amount of control, so I'm not going to hurt myself or my partner, but I can forget about standing up for awhile. And there's no way I could stop the shaking even if I wanted to. Immediately after this type of orgasm, I breathe in tiny, involuntary gasps like after you've been sobbing until I catch my breath somewhat and I still shiver for like 5 minutes.

I love having this kind of orgasm, but I don't know if it's really normal. The first time it happened, my boyfriend was a little scared and thought he might have to call 911. Does this happen to anyone else, and is there cause for concern? less

I am going to be different in my response from those others thus far (as usual). It may indeed be "your" normal..whatever normal is. However, what you describe could indeed represent some issues that are worth following up on. The shaking during intense stimulation could represent deficiencies of potassium or phosphorus, and the swirling rainbows could result from restricted blood flow to the brain or optic nerves. The breathing you describe and shivers could also represent some physical issues worth looking into. In short, have you had a good physical lately to make sure your general health is fine, your blood pressure is good (low BP during that period of excitement would be my guess...nothing but a guess, mind you), and that your general blood chemistry is fine? If you are overweight, there could be some compromised blood flow issues as well. These are pretty intense symptoms you describe during sexual activity (a period of high physiological "stress") and they do sound a bit more "over the top" then what most people experience, thus my advice to have a doctor check you out and make sure you have a total "A-Okay" bill of health. Sure cannot hurt. Be safe, be well. less

Hmm. Well I've gotten my physical for the year and they didn't tell me anything was wrong with me. o.o They never say anything and I have to wonder if it's a bad thing.

I'm about 15lbs overweight. Also I haven't been exercising as much as I should due to winter and all, but I have been getting back on track with it, running on the treadmill and doing my pilates for the past week.

Also I haven't been eating as many vegetables as I usually eat. I've been living with my boyfriend's parents and they never eat them, so it takes some effort to get good nutrition here.

...I hope I'm not dying. o_o; less

My first question is, how long have you been sexually active?"

I think this greatly impacts our physical responses to sexual stimulation; when I first started having sex I had almost the identical reactions and now that I've done it a couple hundred-thousand times, the orgasms are still earth shattering but my body has learned how to process all of that stimulation differently. less

For about 4 years. I didn't used to be so strange though. This is a recent development.

I closed the distance of our long distance relationship 3 months ago and we've been having sex almost every night for those 3 months instead of a couple times a day for 2 weeks and then nothing for 3 months. I've finally gotten the hang of clearing my mind and making myself feel amazing while I'm on top. I don't know if my muscles are getting stronger and that's why it's so good now or if I'm just better at it. My orgasms have just been ridiculous lately, though. less
