[Amante]

For ME:

New partner (casual or serious relationship) who has a removable cock that is an integral part of his/her identity: No way, that would be like someone saying to me that I needed to get new breasts, and to my definition of things shouldn't even be in the same discussion as "toys." Getting a new cock for a cock-centric butch or transguy is part of who they are and not my business if it's new or not.

New partner in a casual affair that's not likely or uncertain to last: No way, because it would be just too damned expensive and impractical.

New partner in a potentially long-term relationship for whom they are TOYS and not an integral part of his/her identity: Once the relationship got serious, I'd prefer to buy new toys, just like I'd prefer to buy some new sheets, a new dress for a special occasion instead of the one I wore for many previous special occasions with my ex, etc. If I can afford to replace certain things that were an intimate part of previous relationship, even if they're still perfectly functional, then I'm going to! Did I ditch all my old sheets? Oh hell no (though I made sure to keep the best ones!) But do I enjoy knowing that the sheets I'm putting on are new or have never been fucked on by anyone other than me and her? Absolutely. There's no moral implication to it - it's a preference, period. And an excuse to get some exciting new things.
