We plan to have intercourse during her ovulation period i.e for a week to have a baby. After having sex for first 2-3 days I can't keep erection further for a week or two. But after 3rd week i can have erection properly without any issue... This is happening from last month. So I am Bit worried whether this is dysfunction or something else. How to overcome this?? So that we can have intercourse for complete ovulation period and increase chances of getting pregnant.
