I haven't dated during your lifetime ... I didn't take the ending of relationships well, so I "retired".
But, when I did, all of my girlfriends knew I liked porn [which at the time consisted of mainly of magazines, super-8 silents and going to the "porno theatre" - though my dad had an early VCR]. I actually got most of them to go to the theatres to see their first pornos - which was an achievement since those places were disgusting!!
The only bad event was when a guilt-ridden Irish Catholic GF threw up during "Ecstasy Girls".
The oddest nickname I had was from a black GF who called me "boo". BTW, she just LOVED the John Leslie scene in "Sexworld".
