yeah, probably a pretty personal thing and a judgment call unless you ask directly.   I'd draw the line around the word "nude".  other areas might be grey, but being seen naked *definitely* invokes the idea of consent.

Yeah, I agree. There's definitely areas where the idea of consent can be murky, but it's safe to assume your ex's nudes involve some degree of consent or lack thereof. It's a bit silly for people to get caught up on that bit just because there's other areas where it's murky.
