These are My Erectile Problems..

i everyone,
im a 20 year old guy (virgin)
my sexual attraction to my girl was so strong that i even used to think that it might not be normal. the Erectile thingy used to happen to me sometimes even by JUST talking!
we are both strict and religious, so we dont want to have sex before we get married.
but when we used to stay in our car for long time, we used to go for LONGE TIME make-out and end up doing what they call " DRY HUMPING ".
but lately, i started taking off my pants, and i asked her to see her front (and she wasnt ok with it anyway).
i also asked her to touch my part (but she wasnt ok with it even though she did it after i asked her alot of times)
till one night, i had the intention to do that DRY HUMPING thingy again, but my part wouldnt Erectile AT ALL!!
i donno the reason, i donno why!
and since that day, my sexual feelings arent there anymore!
i became so depressed after that..

i read that having sex before getting married might have pshycological side effects like not feeling love anymore, or not feeling interested in that person anymore, but the thing is, in my case, its true that im not feeling sexual attraction, and im getting pissed easily now, and im not in the mood for alot of activities that we used to do together before, BUT, i dont want it to be like this! the thing is that no matter what, i want to be with her! and even though those feelings might be lost, i want to find them again! cuz i truly wanna b with her! and i dont wanna be without her!
i cant forget all the things we had together! i cant forget how hard she tried to make me happy always!

and the problem here is, that i dont know whats happening!
can anyone help, PLEASE?

.....

today, she called and she said that she's feeling an annoying sexual attraction in her sexual part, and its not leaving, or, when its about to leave, it hurts her!
can anyone explain what that is? and how to get rid of it? PLEASE!

Thank You So Much Everyone for giving me ur time =)
