men ejaculating inside t/ vagina.

As of recently me and my man have been trying to have a baby, with that being said he's of course cumin inside. My question is, is it normal to have a burning sensation after he cums inside the vagina. Before anyone comments "maybe it's an STD" that's not the case we've been married 3 months and last month I had major surgery which several blood samples were drawn, we're both clean. Just wanting to know if other women experience the same thing.
