no, it does not.
If a guy keeps asking me to use a sex toy on him does that mean he's secretly gay?
The anus has nerve endings that pick up pleasure people! Why is that such a big thing for people to get their heads around? It has NOTHING to do with sexuality. I'm sure if gay guys had vaginas they'd probably use those too - or maybe not?/
Amanda is totally right. Guys like it despite not being gay.
No, sex toys are using to entertain himself in absence of a partner. For example my husband is using sex toys in absence of me which he ordered from online. That does not means that he is gay.
