My Husband wants a 3 some but I am against it.

Sooo my husband has been bugging me over wanting a three some for 4 years now and I’m always telling him no.

1.) I am a mom i have a son (2 year old) and I feel like that wouldn’t be something respectful of me.

2.) I told him I don’t feel comfortable with another person seeing me naked but him

3.) It makes me feel like my body isn’t enough for him that he needs this threesome so badly.

And 4.) He started telling me last night that he believes he’s not satisfying me enough because he doesn’t make me come like he used to and he wants me to be satisfied also. Which I guess it’s true he has been coming to fast but I told him I don’t care I don’t need no threesome to satisfy me. I just want some opinions on this guys.
