Yeah at a certain point you realize a lot of the barriers are in your mind. Though the barrier stopping you from sleeping with someone and their parent is usually in all three of your minds. I recently had a date with a woman who, when she lived near her parents, felt the need to double check potential partners haven’t been with them. And yeah when I went after a (completely different) older woman who had a hot, gay, and age appropriate daughter I assumed it ensured that the daughter was permanently ofd limits.
