I have been out with many girls, but I quickly lost interest because of her work. Didn't care how hot they were.
When they left that line of work, you have trust issues, meaning you think of her of keep doing that on the side given they have already done it.
If you value a traditional relationship which is the only relationship I can see myself in, it's a no go.
For me if I wanted to pass time seeing a girl who would do that on the side I would do it, but wouldn't care if it ended nor would I do efforts.
In the past 2 years I was seeing a girl who had a boyfriend, I found out later and told her to keep seeing his boyfriend, I didn't care. Even dropped her home and told her not to forget to tell him he loved him. She wanted to leave the guy and be with me, I thought that we would end the relationship the same way we started.
Then an SP asked me a few weeks ago to be her boyfriend, even if she was being and SP and also had a boyfriend, I told her no for the same reasons. After a while she became more demanding asking for stuff and tried to establish a boyfriend/girlfriend dynamic. Saw I resisted like hell and she went nuts on me.
So for me it's impossible to take a promiscuous woman seriously. Women get a gazillion requests per day so if it is so easy for them to spread their legs I can expect to be dumped the second they find something better. Really hard to build trust with those parameters.
