I'm twenty, so theoretically I would be able to date anyone 17–26. Firstly despite the age of consent being 16 in the UK, I would stay away from any under 18s, I'm not a fan of angry fathers coming to kill me. The best range is the one you're comfortable with.Also, I would see no problem dating anyone under maybe 30 as a max. So if you’re 13, you can date anyone over \frac$. That means, to find the oldest age you can date, you have to double your age and take away 14. ## Free sex chat mecico - Formula for age dating For instance, you might want to know what the oldest age you could reasonably date would be. The rule doesn’t say anything about that, but it does also apply to the other person. We take away seven from each side to get$y-7=x \div 2$, and then double both sides to get$2y-14=x\$.

Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross culturally.

There are also alternative social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.

Two things: the somewhat random-looking picture above is from The Moon Is Blue, a 1953 film that’s the first known reference to the ‘dating rule’ discussed here.

Secondly, I don’t make any judgement about the validity of the ‘dating rule’ – you might find it a useful rule of thumb or a ludicrous restriction; I find it a nice thing to do some algebra on.

According to internet lore, there's a mathematical equation that governs the lower bound for the socially acceptable age of a potential dating partner: half your age plus 7, or, in mathematical terms, if x is your age then the lower bound is f(x) = x/2 7. if you're 20, then the minimum socially acceptable age for a date is 17.

But it was The Ragbag who pointed out that this rule has a duality: for the date to be socially acceptable, the rule must be adhered to by your date as well.

There is a so-called rule about dating: the youngest age you are supposed to date is half your age plus seven.
