My first wife suffered from vaginismus, which is a painful contraction of the muscles when physical contact occurs (ie, penis trying to get in). It can be fixed, but it was a contributing factor in ending our marriage. I'd find a good female doctor and have a good talk about it. Don't let this drag on.
This.
Also there's a show on TV called "Strange Sex"..they did an episode on that. Te woman was brought up in some strict religious family where even using a tampon or going to a gynocologist was "evil". It took weeks for them to use certain techniques and it went away completely. It's probably stuff you can do yourself.
I really appreciate your replies to my not-serious-sounding but very serious question. Lol.
