Struggling to orgasm 😩

Just wondering if anyone else has had a similar experience and if so when did it get better? 😩 I'm 6 months pp with my second baby, had a nexplanon implant fitted 5 months ago and I'm still exclusively bf so I know hormones likely have a big part to play in this... I'm really struggling to reach orgasm both from sex and if I do it myself. I get close and then it goes away, rinse and repeat. It's so frustrating. I've never experienced this before, I'm usually one of the lucky ones that can orgasm pretty easily from sex and it used to happen at least once every time I had sex. I feel awful for my husband as he thinks it's something he's doing wrong or that he's not good anymore but that's not it at all as I'm in exactly the same boat if I try to play solo! Sex still feels amazing it's just awful hardly ever getting that release 😅 took 45 minutes of riding last night, my poor husband was hanging on for dear life 😂
