I remember a relationship I had with a 20 year old, I was over twice her age. She came up on a casting, fucked me in the first 30 minutes and stayed the night. While she was living with another guy she was coming over to me 3 times a week for sex.
She then went back to her real home and started phoning me to come back. So before you know it she's back living with me and I'm paying for her classes. The sex was great she even liked threesomes with other girls.
But with an age gap and culture difference like that it's doomed to failure.
