I've heard that "half your age plus 7" rule being applied to both genders as the acceptable age gap rather than any sort of ideal. Let's be honest though, there are plenty of men and women who have very specific age range requirements. As Snape says, its probably something to do with the power dynamic, but I also know many a woman in their 40s who've given up attempting to date men in their 40s (or even 50s) because those men will only consider women in their 30s. These women are playing the men at their own game and toyboy dating sites are flourishing as a result. For those of use who stick to sensible age differentials, it does make the pool much smaller (not something I need to tell any dating regulars). My range is 10 years up and down. Like Snape I will admit that I've not dated anyone the full 10 years older recently (although I did when in my 20s) but have shagged dated someone over 10 years younger. But as he was 38 and a soldier already a grandfather I didn't feel like I was stealing his youth.
Lovely to see many many new people and please forgive me but I'm not going to be able to namecheck. It is fabulous to hear new experiences and views though, really fabulous 
In my dating news, I'm seeing a couple, talking to a couple and shagging a couple One, who I'll call Pawnee (he's had knee surgery ) looks to have the most potential, however he's now got a partially blocked stomach to handle along with the crutches. But he appears normal, keeps in touch with me with the appropriate regularity, remembers what I'm doing and is remarkably inventive and active despite the knee But its all BS until it isn't ...
I soooo love this thread, it keeps me sane
