Ok so I have seen a lot of you in her asking the same question." How do I get rid of that horrible smell after my SO cums in me ?" I recently had this happens to me , my SO other had cum inside of me u didn't smell anything the first time I went to the bathroom but the second time I did which was a hour later . So what I do was take a shower and washed my lady areas with feminine body wash  (summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>) . I went to the bathroom a few minutes later and the smell is gone . BTW if you take a shower after sex it makes you feel fresher so I would try it if you don't already :) . I hope this helped
