orgasms aren't as intense

I use to have very intense orgasms, like felt it in my toes intense. For a few months now it's been taking me longer to orgasm and they are not intense at all and I feel like I'm not satisfied after. My husband isn't doing anything different (not a bad thing) and there have been no changes. I had a baby last July (2016), but it didn't start until 5-6 months after I had him. I've even tried giving myself a few and they feel the same as when I've always done it myself (I can't give myself intense orgasms like my husband does). Toys don't make a difference either. Is there something wrong with me?
