First it started like a ring, so I thought ring worm, then it has just taken shape all over in the corner of my inner thigh next to my groin. I also get a fishy smell at times (depending on time of menses) during sex.

My husband, has a small bump on his genital but it doesn't seem to bother him.

We are trying to conceive and we haven't yet. Could it be that I have an STD that I was unaware of or even him?

Maybe it is a yeast infection. You can get one anywhere, jock itch for a man

I had a similar case and I'm celibate!
I got it from riding quads


It could just be irritated! By all the sexual activity same with the funny smell


Also try and figure out who got what first
Your husband with the bump or you!?


I wouldn't want you to assume anything about your husband but you never know...

In either case go to a Dr. you can never be to safe!

The fishy smell accompanied by time of menses as well as intercourse sounds as though it may be bacterial vaginosis. Time for a doctor's appointment for a proper diagnosis and treatment.

Red rash which looks like a ring and widens over time is characteristic for Lyme disease (Borrelia infection), usually contracted from a tick bite.

Another possibility is a staph infection - cellulitis on the thigh and vaginitis (causes a fishy smell).

If it doesn't stop in few days, you might want to get an official diagnosis. You may also try with OTC antibiotic ointment. If it is staph, it should help in a couple of days.

I had the same problem too. And it itches me like no tomorrow. Especially my mons area. Hope I ill go away forever.
If its ringworm, try applying virgin coconut oil. It helps
