stress would be the most likely cause. you are correct. get back to your normal sexual routine reassure your wife that you love her and are not thinking of someone else and put this isolated incident aside.
is it normal to lose an erection during sex once in a while? . around the first of the year my wife and i were having sex and she suggested we try a different position. when we got adjusted and ready to try the new position i lost my erection. she thinks it's because i don't love her anymore and that i was thinking of someone else even though i've told her every single day that i do love her and always think of her. we didn't have sex again for a couple of weeks after that and kept my erection. i think it's due to stress. please advise.
