Orgasm question

Okay so my boyfriend tells me I'm "broken" because I've never actually had an orgasm.... however I believe I get the build up of one but nothing actually happen from it... I've noticed every time I get the build up I get a runny nose after but I don't know what this means... I never played with myself growing up, I actually just started... so I'm still figuring things out... but he is starting to get a little frustrated with me because we'll do things most girls will go absolutely crazy for and nothing.... no squinting or orgasming... please give me advice...

And when the build up occurs we don't change anything we keep going at the pace we were, the position we were everything remains the same...
