why am I not feeling it?

The first time i tried E was at a rave around a few months ago. My friend Remmi had some molly and suggested that my friend cruz and i try some. I thought, what the heck, my boyfriend does it sometimes and it looks like he is in wonderland, ill try it too. so My friend cruz and i parachute the molly. 2 hours later we are not feeling ANYTHING. just super awake. Cruz gets annoyed and goes outside for a cig. when he came back in he was rolling like no other. he suggested that i smoke too maybe itll bring on the roll. well i tried a cig and it didnt. i smoked alot of weed and still nothing. i wasnt even getting that high. disappointed that i wasnt having as much fun as they were, i went home. 

the next time i went to a rave cruz and i got 2 E pills. we both took one, felt the roll for 5 minutes and then it went away and was just super awake. I gave an extra pill to my friend Damien and he was rolling his balls off. at this point we thought it was because of our weight and because damien was much skinnier and shorter than us. 

Cruz and i waited 4 weeks before taking our third try at E. We went to my dads empty house to spend the night and roll and play music loud. we ended up not feeling anything, pulling an all nighter and feeling completely depressed making it a terrible night. I mean, maybe E isnt my thing but i wanted to at least feel something.

after trying it a third time with no luck i ended up getting the E from my friend who rolls all the time. felt funny for 10 minutes and then it went away! 

I decided to try E again a fourth time, we chewed it. and then when the first one felt like it was hitting me, i took another. (parachuted) so did cruz. He felt nothing and I felt amazing for 30 minutes then it went away. after that i smoked weed and felt great again for another 20. then it left completely.

I took E for the last time last  night and we decided to plug it. yes we used a syringe and shot the pill up our asses with a drop of water with the crushed E. we got it in there pretty deep and layed on our stomaches for 30 mins. when we got to the club i didnt feel a thing and my pupils were not even dilated. i fell asleep right when i got home like i didnt even take E that night.

*every time E was taken on an empty stomach
*every time we would take vitamins and prepare for E
* I am 5'0 and weigh 140
* cruz is 5'9 and weighs 200
* damien is 5'0 and weighs like 110 
* we got the E from different friends every time
* we knew it wasnt fake since my other friends rolled and we didnt
* we dont take any meds (except for cruz takes epilepsy meds but idk what they're called)
* we smoke weed alot but that probably has nothing to do with E
*pupils got big every time except when i plugged.
* i know were doing it right because our friend parachuted and felt it alot.

I need some feedback, what do you guys think? shouldn't of at least me or him felt it already? are we prone to feeling it?  i want to know whats wrong with me and why im not feeling it. 

i also was very excited to go to the DEADMAU555555 concert.... but now its like ehh. its in 8 days and i really was hoping to finally roll.  but who knows what'll happen.
