Mazal tov on the birth of your baby!
We are sorry to hear of your
pain with relations. We suggest using a lubricant, which might help reduce the burning sensation from the semen. Another possibility to explore is seeing a urogynecological physiotherapist to see if that helps.
If those measures do not suffice, it would be possible to use a
condom with a hole in it at the tip. That would enable sperm to get through, but reduce your exposure to semen.
Please write back with any further questions.
