My mate is currently going out with a 37 year old grandmother, but it's not a great example because she mings.

ukey: I'd let him off if she had a winner of a personality, but she doesn't. I'd rather wash my balls with sulphuric acid and dry them with sandpaper than have a conversation with her, much less fuck her.
In contrast, I used to work with a lady that the last time I saw her was 53 and hence old enough to be a grandmother despite not literally being one, even though her kids are old enough to have children of their own, and I'd have slept with her in a heartbeat. She was lovely in the face with a youthful vitality, very flirty and she had a wazzo pair of jugs. :boobies:
So like a lot of questions it's highly subjective, but "being a grandmother" would definitely not rule a lady out for me to romp with.
