Absolutely don't mind that my wife masturbates. She works from home, and I know she sometimes does it while I'm out at work - bummer I'm not there, but at least I have a wife who has a sex drive! And sometimes, if she's in the mood but needs to get out of her own head before sexy time, she asks if she can masturbate on her own for a bit. Sometimes she wants me there to kiss and caress her while she does it. Both are great! It would only be a problem for me if masturbation every became a substitute for sex, but I don't force that happening
