Apart from women who believe masturbation is akin to cheating, I disagree any stigma exists about male sex toys. If anything, I think women are curious, but this tends to be an area of male sexuality men hide, Ime.
Personally, I enjoy watching men use sex toys, have purchased a few for partners, and used them with him as well. Never did I equate the toys with deviance, just as most men, save the nut cases who, again, find masturbation threatening, would find my dildo fun time hot, not problematic.
