TMI!!! Sex while pregnant

Ok so I’m 8 weeks and 2 days , and my vajayjay is very very sensitive when me and my husband are having sex. What I mean by sensitive is that it hurt after we’re done, like the skin around the vagina is swollen .! I had this before in my last pregnancy but never talk to no one about it. Do anyone else also experience this ? (No std no diseases) also after sex I have to put a cold towel down there lbs.... but my vagina would be back normal couple hours later.
