Husband only cares about his sexual needs not mine.!

So my sex life with my husband has majorly changed since having our child, he has become extremely lazy when it comes to satisfying me and has vocalised he doesn’t want to or does not care after his needs are met.

We have kinda stopped having sex in general because I don’t feel the need or desire to have sex with him if that’s his mentality towards it.

So fast forward a few weeks now I’ve bought myself some sex toys and wanted to know if it’s wrong to hide them from him and not actually tell him I bought them.

Am I selfish for no longer caring about his needs and purely wanting to satisfy myself when he isn’t there ...

is it wrong of me and will this ruin our relationship ?

I’ve tried sitting down and talking to him and he just says that it’s weird I don’t come from penetration and every other person he has ever been with has and it’s my fault also that he doesn’t want to satisfy me because it’s a chore to him and has no interest in me at all after he is done.
