I often get the trouble during regular sex with no drugs. But this never ever happened during sex on MDMA. The rhythm is so perfect it reminds me of the Gattaca movie.

Some times I had the tachicardia episodes right before taking MDMA because I sort of get nervous (positively, like when you are about to meet a friend you have been separated from for years, because I look forward to such an intense love experience) but they stopped and perfect rhythm restored immediately as MDMA started to act (as I could notice).

So I feel like I should probably carry a reasonably small crystal of MDMA with me wherever I go as it can save my life once - this probably outweighs the risk of criminal prosecution. But I still am not sure, I still hesitate to have any prohibited substances with me, store them at home or anywhere.

I have also tried 6APB once - a guy has told me it's a "better MDMA" which doesn't stress the body that much. Besides I didn't really like it I have also found out (I wouldn't ever touch a drug without studying whatever information I can find about it) it is supposed to be 50 times more cardiotoxic and should never be taken together with viagra - combining these 2 drugs can make you need heart surgery after just a couple of times you take it.

But the only people on those vasodilators will be really old, or taking them to loosen their anus.

Not seeing how the sildenafil is contributing to a problem.
