No condoms during sex cause smell?

Frankie • Mommy of 1 beautiful little girl and one on the way. I have an amazing husband!! Nursing student, 22 years old
I usually have no problems in the smell area but now that I'm in a serious relationship my boyfriend and I don't use condoms and I've noticed a weird smell after sex and even after a shower... And I use summers <a href="">eve</a>.. I just had a check up there were no abnormalities.. Is this common?
