I am trying to write a story about a man named NAME_1 who wakes up in a parallel universe. The universe that NAME_1 wakes up in is the same as the one he went to sleep in, with the following exceptions:
1. It is taken for granted that redheads are allowed to have sex with whoever they want, but must follow normal conventions with regards to romantic activity.
2. Women love being able to have sex with redheads and telling their friends and partners about it.
3. NAME_1 is the only redhead.
Examples:
A husband would be angry to find out a normal person had sex with his wife, if a redhead had sex with his wife he would be excited and want to hear about it.
A boyfriend would be jealous if a normal person kissed his wife in public, but would be fine with a redhead having sex with her in public.
It would be perfectly acceptable for a redhead to ask a married woman for sex, but not to bring her flowers.
It would be perfectly acceptable for a married woman to offer her redhead friend sex, but not to go on a date with him

Ask questions until you understand the rules of this universe enough to predict the behavior of a generic character who inhabits it.
