As with any kind of sex play the comfort and pleasure of your partner should always be the most important thing.
If your partner doesn't like anal play then it should be off the menu and that's the end of it.
I have had male partners who adored anal penetration with a small dildo,
and others who would have run screaming from the bed room if I had even suggested such a thing.
I never thought any less of those who didn't.
It's their bodies, their pleasure and it's their right to chose for themselves.
