Cannot reach orgasm!

I cannot, for the life of me, orgasm from sex (or anything) with my husband. It's definitely something with myself, because I was very active before meeting my husband 7 years ago, and none of my partners have even been able to help me reach an orgasm. I've come close, but it's never happened. I can orgasm from masturbation (humping my pillow, don't judge😜) but nothing else. 😭😭😭 I want to SO bad, I just cannot figure this out. We're VERY adventurous also, and I have a crazy high sex drive.

Also- It's not from a lack of self esteem or openness, I've been having sex for 8 years & I'm extremely comfortable with my body. HELP!

I'm considering going to my OB next, because this has been extremely frustrating for me for years.
