We have been trying for a while and my husband sometimes has this issue. Im not sure if it actually affects our chances of conceiving or not. Bit awkward to ask but i really wanna understand.
It can make timing harder when trying but its usually manageable with the right help. Please dont feel embarrassed to see a doctor about it, they handle this commonly. Dont let stress make it worse either.
We faced timing issues too when trying and it stressed us out. What helped was actually talking to a doctor instead of googling at night. They reassured us a lot, so I'd say go that route.
This is something better discussed with a doctor honestly, it can have many reasons and most are treatable. It doesnt have to mean you cant conceive. A doctor visit will sort the worry out properly.
Dont panic over this, it happens and often stress is a big reason. The best step is to consult a doctor calmly together. There are good treatments, so stay hopeful.
