Thanks for contacting HCM with your medical concerns and questions. You are concerned that your boyfriend is having problems with erectile dysfunction and premature ejaculation. These are two common problems men face. This can be related to stress both positive and negative stress. If he is an anxious person then I recommend he find ways to relieve the anxiety wither through yoga, exercise or relaxation exercises. To help with medical aspect of erectile dysfunction I usually recommend seeing his doctor and getting a prescription to Viagra or similar medication. This will help him maintain erection and may improve his confidence. The premature ejaculation may improve just with being able to maintain erections. But if they do not then I recommend using condoms and special male lubricants that have mild desensitizing agents. This may allow for longer time before ejaculation. Then if that does not help then there are medications called SSRIs or fluoxetine that help with premature ejaculation. The SSRI may also help with anxiety and depressive symptoms if they occur. Hope this answers your question. Please contact us again with your medical concerns and questions
