im betting you wont get another answer like this one.
actually if you want to know the truth, hes undermining your sexual relationship by using his hand all the time. cuz lets face it; you will never feel the same on him as his hand does. his hand can do it exactly the way and in the spots he wants it. so anything else is going to make it a lot harder to finish the job, if at all. you are going to end up with a husband who cannot finish with you because hes spent so much time doing it himself.
you should check out mark gungor. he can seem pretty harsh, but hes got some real good information. basically feels the same way as i said above. if a man needs it he should be looking to his wife first, not his hand or scum magazines. what good is that for your relationship ? not good at all. hes just conditioning himself to not be as sensitive for you and to only be able to perform to his hand. doesnt that sound like a wonderful thing for your marriage. (sarcasm)
my husband eventually burnt all his magazines and smashed and trashed all the movies he once had. our sex life has never been better than since he quit doing that so often and relied on ME for his sexual gratification. because, after all, thats what its created to be like.
one side note; even if you dont feel like it, unless you are seriously ill, dont turn him down just because you dont feel like it. just do it, even if you are just doing it for him. ;) every time i give in to my husband, i end up enjoying myself just as much as he does even if i didnt feel like it at first. its the most selfless thing you can do for your husband and your marriage :) :)
