this can be a complicated issue but yes anxiety could be one of the major underlying issues. made worse over time. it would be in your best interest as a couple for him to see his medical provider first (to rule out any organic reasons) perhaps followed by some couple counseling. you may have to lovingly coerce him to do both.
can anxiety keep a man from being able to ejactulate or maintain an erection? . my boyfriend knows that him not being able to ejaculate whenever we have sex makes me feel like it is because i am unattractive. he was not sexually active for several years before i came along. is it my fault in the sense of making him worry so badly about not being able to and upsetting me that he loses his erection altogether?
