Can't orgasm through penetration while having sex eke

I Can't orgasm when I'm having sex with my husband but I can by myself.. why is this?.. I can orgasm through Masterbation.. both through penetration and by pressure on my clit.. I can have up to 4 orgasms through Masterbation.. I have never had a orgasm with any past boyfriends or my husband.. i try every time through sex but just can't.. I love my husband so much but I just can't get off.. I get to the brink every time more then once but just can't cum.. it's really frustrating and upsets me.. but just can't.. does anyone else get this problem.. I need help 😔
