UTI&Pain

This is my first time being on Glow and so far I'm loving all the details and forums it offers. So my husband and I have been separated for a year due to marital issues. We have recently decided to work on the marriage with couples counseling, bonding, dates etc. I have not had sex this whole time and recently became active with him again. The problem is 1. Sex is somewhat painful 2. I think I'm starting to get a UTI  3. The sensation isnt the same. 

What can I do? Is this normal? 😕
