There seems to be some white lumps coming out of my fiancee's vagina during intercourse? should we be worried?

Multiple reasons : Sometimes there can be multiple reasons ,it can be STD or simple skin moles ,I will advise you to see your obgyn

Concern white lumps: Good night, I read your post. The white lumps you’re referring to could be related to discharge and a possible STD, as well as condylomas or genital warts. Either way, I highly recommend your fiancé to be evaluated by her Ob/gyn, for an in-office exam. Protective intercourse is always encouraged.
