Thanks for contacting HCM with your medical questions I hear that you are concerned about having erectile problems just before your marriage. Masturbation did not cause your erections to get less nor cause your penis to shrink. More than likely your anxiety and stress related to your up coming marriage is affecting your sexual performance. I recommend that you reduce your masturbation to better focus on your new wife. Also doing more relaxation and meditation may also help reduce your anxiety. Hope this answers your question.
