Sexual orientation is irrelevant.
People like to complicate things or jump on moral high horses. "poor me" stories, "she doesnt love me any more" whatever. Grow a set and deal with it. Life isnt always rainbows and fluffy clouds wrapped in IronWarrior style bedlinen - sometimes u have to work through the hard times and those times are what define u as a person.
Snaking off to some website to organise trysts is premeditated plain and simple. you cannot even cite "your honour i was drunk and her boobs were a flapping in my face".
Ergo in your premeditation you accepted that there could be consequences for your frolics
Have you considered that gay people who live in countries where homosexuality is illegal use sites like this to meet?
