Husband never masturbates!!

I dunno if this is good or not according to my husband it's good he doesn't HAVE to, he says and I quote "I don't feel the need to bash the bishop our sex life is great". It's true we have a good sex life but all my ex partners still used to have a fiddle. My husband never even checks women out of goes on porn or nothing I know this because he's either here or at work and when he's at work his phones off all day and his contracts I. My name n when his bill comes through its itemised!.. I'm greatful for that tho don't get me wrong!... He's 33 I'm 25... I have a high sex drive so sometimes even though the sex has been amazing I still masturbate... Call me a perve if u wana but I kinda find it quite a turn on watching a guy play a bit (obviously not just any guy obviously I mean a partner when in a relationship)... But I'm 100% serious n can't stress it enough... The whole time we've been together... Not once has he played with himself...  It is sweet knowing he feels he doesn't have to n it satisfied sexually n we r hunky dory basically what I'm askin ladies is for his age is it normal? And in general... Is it normal he literally NEVER does it... ?
