Yes, because that is the Priest's job and that job comes with certain lifestyle choices. We would talk about their job every day because we are in a relationship and talk about our lives and if the relationship got serious it would be a problem that I wasn't religious.
Not necessarily.
The point is whether their profession sets the tone of the relationship.
You can be in a perfectly normal relationship with a priest, just like you can be in one with someone of any other profession. Or you are too immature to realise that sex workers don't strut around in lingerie all day and aren't horny 24/7
Even the "head Domme" who last year told me her relationship was 24/7 femdom and she only liked submissive men has since said she is open to a vanilla relationship
