My boyfriend said he felt bad about feeling my boobs ??? :/?

He is nervous and never touched them before. He doesn't want to hurt you or advance the relationship too fast for you. Do him a favor, straddle him again and take your top off. Let him get the full view and let him know you are comfortable with him touching you. He is nervous and you have to help him understand that he has nothing to be nervous about. Give him confidence by leading him into the first stages of physical intimacy. Being as you are 16, keep it above the waist for now.
