My boyfriend is a generous lover and always makes sure I'm satisfied, especially when we don't have protection, he makes sure I always get there. I feel really bad that I can't do the same for him, especially during that time of the month and we can't really do anything below the waist. I've tried to give him a handjob, but the second my hand grasps his penis, he tells me it's not a good idea and when I open my mouth to ask him why, he kisses me until I forget what I was about to ask him. Any suggestions as to what I can do? I don't have much sexual experience, so I am clueless here. Not that I'm ungrateful or anything, but I feel bad because I don't do anything. Help please!
