Uhm. No. A toy is an inanimate object, whether it's a lifelike dildo or a 700-function vibe. Unless it starts listening to me rant about my crappy day & brings me soup when I'm sick, etc. it's got nothing whatsoever to do with whatever relationship I may have.
Besides which, a lot of guys like seeing their partners play with toys or using them together. In that case, I'd probably go for a less realistic toy just because I'm straight, thus dating straight guys who don't really want to look at other dicks. But, that's just a matter of being considerate, not concerned.
