Alternative to PIV Sex

I got a lot of helpful responses to my vibrator post – clearly this is a great group to get feedback from. My wife struggles with LL issues but we work through them well due to good communication and lots of other things. There are times when she’s not in the mood, and rather than guilt her about it, I’ve thought of an alternative. Her pussy is beautiful – absolutely perfect in look and feel, anytime we’ve got the lights on, she can lean back when she’s on top and that about does me in. I was thinking of proposing jerking off while looking at her pussy as an occasional alternative. Is that weird? I guess it feels weird in a way that looking at a picture or video wouldn’t. Anyone got any experience or thoughts on this?
