Absolutely not.
Ever read the newspapers? There have been cases of guys who make
their girlfriends take naked photos of themselves. And when the
relationship is over, the guys blackmail the girls using the
pics.
And even if the two of you don't break up, ever thought about what
may happen if your bf loses the pics and they fall into the wrong
hands? (Hint: Tammy.)
In the first place, if your boyfriend was such a nice guy, he
wouldn't have asked you to take naked pics of yourself. He is
asking you to do this out of lust, not love. He sees you as nothing
more than a sex toy for his own pleasure.
I say dump this jerk and find another guy who knows how to respect
women.
