Here's a pic of a rash on my hand since 2 days which has faded a bit now.. I've got this kind of a thing before many times but not of late, we call it ringworm. Also, I've got some other red spots on my shoulders because of the excess heat/mangoes but they're very different from this one.. My sexual history is as follows: -Had my first kiss in January -Sucked without condom on a virgin, completely trustworthy guy last month for 10 seconds (didn't swallow) Now, the more dangerous stuff.. -Hooked up with a 31 y.o. random online 3 weeks ago, sucked him off with a condom and he fingered my ass with his saliva.. -Hooked up with a 29 y.o. slutty guy last Saturday, did nothing more than kissing, but his precum was dripping above my anus during foreplay.. -Hooked up with a 3rd guy last Sunday (and yesterday) and he fingered me with saliva and also sucked me off without a condom (but just yesterday).. he also accidentally very slightly penetrated my anus with a condom last week while pseudo-fucking.. I'm getting very panicky..
Priorities: 1. Go get tested for STD/HIV, seeing as you have a sexual history, and I assume you also haven't tested yet. 2. Ask the doctor what he might think it is, seeing as it looks like ringworm or another type of fungal infection. I had something that looked similar to it. It was like athletes foot, but it was under my arm. Be sure to keep the area dry, and make sure your doctor doesn't give a misdiagnosis. If the doctor can't make a diagnosis, ask if you can get referred to a dermatologist or another type of specialist.
Let's be honest, you should be going to see a doctor for real medical concerns. You have a history, and that's cause for concern, and early treatment for any STD is good. In the worst case scenario, it's nothing. Good luck!
There's really two questions here: Regarding the rash- that doesn't look like ringworm. It looks more like eczema that was scratched or an abrasion. Ringworm has a very distinct appearance: http://www.howdoeslooklike.com/wp-content/uploads/2012/11/Ringworm-6.jpg If the rash persists, you can have your doctor look at it. Regarding your sexual history- Anyone how is sexually active needs to have STD testing, especially if you're hooking up with multiple partners. But that's probably not related to your rash.
