NSFW warning if you aren’t keen on shared intimate information

You may have, but also check the scent of his semen first. Funny story, I had a partner who was vegetarian, his semen did not have a strong scent or flavour. Some years later my new partner had incredibly strong scented semen... it’s always a possibility!

BV also changes the consistency of your normal discharge to a more watery form, often with a very slight green or greyish colour. The smell is one of the first indications though.
