Hello, Welcome to healthcaremagic.com, Before labelling you as erectile dysfunction i would rather suggest that you might be having only performance anxiety. This develops usually while having sexual contact with your partner whom you might not know well, with whom you are having coitus for the first time. Hence when you were trying to have sexual intercourse with your wife, due to this anxiety you lost your rigidity hence could not perform well. This vicious circle will go on hence increasing anxiety and ultimately resulting in sexual dysfunction. I would suggest you to develop sexual skills and communication skills with your partner. Use Master and Johnson technique to enhance your sexual performance. few tips for that: 1. hold talks on neutral topic, 2. have a healthy foreplay before sex, 3. equal participation of both partners to be ensured, 4. explore each others sexuality, each others stimulatory areas. 5. be slow and gentle while penetrating and thrusting, 6. keep discussing about what ever you are feeling. these few things will help you in reducing the anxiety, hence improving your sexual performance.
