Hey, just wanted to add one thing to what everyone else has posted. You said;
(So is it wrong to say no, if he loves me enough to not do it, shouldn't I love him enough to do it?)
Totally wrong reason and would just lead to so many more problems! Perhaps you could agree to being open to the idea if you both are in the right situation, at the right moment, and, most importantly, with the right people.
I think if you found a couple just like yourselves, with the same desires and apprehensions, it might be rewarding to both of you to exchange thoughts. There are lots of couples around with the same fears and desires and, after you become friends..., who knows?
