Ideal size would be around less than 1/2 of a cm tall. Small enough to go unnoticed.
Ideal scenario would involve being shrunken by a date and subsequently lost, where I come in contact with other men she has shrunken and lost around her apartment (colleagues, exes, plumber, etc). The tiny men try to survive/escape while resisting a voyeuristic urge to approach the (attractive) giantess, eventually getting exterminated in the process (unaware).
She comes home and removes her clothes before heading to the shower. I run immediately toward her sweaty, worn white socks and sniff while beginning to pleasure myself before discovering a fellow tiny-slave who had been worn and crushed into the sock earlier throughout the day, begging for freedom
