If you're over 20, you should be allowed to fuck whoever you want. I'm an adult, you're going to tell me I can't fuck this dilf or that milf? Ok liberal. The only exceptions have little to do with age, and has to do with specific power relationships, like a student and a professor, a client and an attorney, etc. As someone in their late 20s, I find a lot of older people hot, and I know my female peers also find 40 year men hot, so what am I to do? Tell my 24 year old friend she can't find a 40 year old hot.
I think if you're a 20 year old who wants to fuck a 40 year old that's fine. I think if you're a 40 year old who wants to fuck a 20 year old....well...that's not a crime but....that's kinda gross.
But at least it kind of makes sense, everybody at least has a chance to naturally be in the same peer groups and for general contact to develop into romantic/horny thoughts.
If the older person has to wait all day in the high school parking for the final bell to ring to get a date... seems like that's a bit much to tolerate.
One of you needs to get on a space craft flying near the speed of light until relative time dilation makes one of you older objectively and the other older subjectively.
It would be really funny if the authority sex havers had to report to was an incel. Just clocking in and getting bombarded with people bragging about getting laid.
