As far as the weave thing, I'm not a fan. In fact, I can be an assh#le about it at times with women I date/dated. I prefer women with hair in its natural state.
If I meet a woman and I'm cool with her hair, then she decides to put a weave in, then I would make a comment if she brought it up. I wouldn't say anything if she never brought it up. But if she says something like "Yea I just changed my look. Do you like it?" I would respond with "Well, honestly I prefer your natural look, but if that's what you like, then that's you." This crushes the weave excitement. And I've been guilty of making off-handed comments about other women and their natural hair while out with a young lady...yea not nice.
Even while dating my ex, I ingrained the natural hair look. When we first started kicking it, she rocked a perm. After about two months, she was rocking that fro. And even a year after we broke up, she still rocks that fro. Saving one permed scalp at a time.
Peace
