Orgasm help?

Samantha • Ohana means family and family means no one gets left behind or forgotten.
How long does it take to reach orgasm once that tingling sensation starts to really kick in? I'm struggling to orgasm yet get to that tingling stage where I just full on grab and cling to my boyfriend. I know I'm close enough and I just need to let go but how do I just let go? It puts me down slightly after sex but my boyfriend doesn't know it does cause I want to know what it's like?
