I was dating a guy for awhile who had a vasectomy. The last time we were intimate was the last day of my period and ever since then (4 weeks ago) I've noticed a different odor down there that didn't smell bad, just not me. He has not had any STD-like symptoms. After my most recent period, the odor got stronger and now there is a pasty white discharge that I've never had before. There are no sores, itching, burning, or pain. I have a doctor appointment in a few weeks but have been racking my brain to figure out what's wrong and worried if it's an STD. Any advice, similiar issues, or recommendations? Thanks!
