Welcome to Healthcaremagic.
The problems you have do not affect the fertility
.The problem you have may reduce the sexual satisfaction but not the fertility.Since you are ejaculating inside your wife there would be no obstacle in her getting pregnant if your semen is normal.
Do get the semen analysis
done If the count and all other essential parameters are normal in the semen then there is no need to worry.
Also do consult the sexologist
who can asses your problem and counsel accordingly.
Wish you good health.
