Did you know churches blessed gay marriages in the 'Dark Ages'? The world's oldest porn, which dates back over 3,000 years, features both male/male, female/female and male/female couples.
The oldest ever known chat up line was apparently said between two men. A mythological story from the 20th dynasty of Ancient Egypt is between Horus and Seth, who quarrelled for 80 years on who should rule. Seth attempted to persuade Horus to sleep with him, saying: ‘How lovely are your buttocks! And how muscular your thighs!’ They then have sex.
