I have a picture from a home video of my boyfriend having sex with a previous partner and I noticed bruise like marks on her vagina near the opening. They are deep purple and the edge of the marks are yellowish green and they appear to be raised. I am concerned that this is a sign of an STD. She is an IV drug user and he did used condoms but I have never seen or heard of such marks. I can email a picture if that will help anyone to determine what it is. Thank you

Please, no need to send a picture.

I would close your legs until he shows a clean STD report. There are some that could present like that, but it could also just be bruising. If that's the case, I would be curious as to why she had the bruising. Is he a rough rider, or is it something else? Regardless, your health is more imporant I would make sure that you're clean and that he's clean first. Than sex can resume.

It could be STD, or very ruff sex, or other issues.

I agree, get a check yourself. And require boyfriend to do test, and see results

It is a great idea, for anyone, when they get a new boyfriend, ( even if he says he is clear) to get a health check.
