Alright I’m gonna try this hereditary math…

So these kids will have the same dad, making them at least half siblings.

Their moms are sisters making them first cousins.

So what are they like 3/4 siblings…?

I’m not sure I follow.

I’m starting from the assumption that OP genuinely wants to talk to women without being creepy (for lack of a better term), presuming that comes from his intrinsic association between “talking to a woman” and “attempting to establish a romantic relationship with that woman.”

That’s a thought that’s undesirable and presumably persistent. Sort of the definition of “intrusive.”

I’m aware that the pop psych understanding of the phrase is specifically about violent or violence associated thoughts but those are the ones more people have and that probably are more disturbing than annoying.

When your parents say, “did you talk to any of them,” they mean did you strike up a conversation with a woman with no presumption of potential romantic outcome.

When you say it, it seems like you’re assuming there’s a potential for a romantic outcome in every conversation between heterosexual men and women.

Your goal should be to strike up a conversation with a woman about random topics of interest, including very shallow ones, with no expectation that you’re evaluating her as a potential mate, and she’s not evaluating you.

Yes, we’re all subject to intrusive thoughts so from time to time, you’ll fail at this goal and start thinking about a romantic path. That’s fine. Just acknowledge it to yourself and endeavor to do better.

It will probably take time and practice. Give yourself grace to try and fail and learn. You’ll know you’re succeeding when you realize you had a conversation with a woman without her gender being a consequential thought in your mind.
