 [ Symptoms ] 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 is because i do not love her anymore and that i was thinking of someone else even though i have told her every single day that i do love her and always think of her we did not have sex again for a couple of weeks after that and kept my erection i think it is due to stress please advise [ Disease ] 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
