Light bondage adds variety to relationship

My girlfriend likes to engage in a little light bondage, tying me up and blindfolding me, etc. 

It’s fun, but it makes me feel prudish because I’m not as adventurous as her. How much should I experiment? I don’t want her to get bored, but I worry that if our expectations from sex aren’t aligned the relationship can’t last.

Couples who are mismatched sexually are often mismatched in other ways too, but your relationship is not otherwise discordant so I suspect you are over-thinking this a bit. In the greater scheme of all things relational, one partner being a bit more sexually adventurous than the other is generally not a deal breaker. In fact, many of this column’s regular readers would give their eye-teeth to be tied up and blindfolded of a Saturday evening.
