Red burning rash on on both side of groin

[Jdoe5150]

Ok so let me start from the beginning- 2 years ago I ripped my frenulum on penis right near the head. Ever since if I masturbate too much or have sex too much it get's sore- like raw feeling and sometime confuses me as to where the pain is coming because it feels so close to the tip. -
I had unprotected sex 3 weeks ago- Felt fine
Day 1- two week mark I felt a sting- not burn- but pinch at my penis tip- urinated frequently- no painful urination- no odd colors- no other symptoms except that slight pinch at the tip when i was NOT peeing. I rubbed my frenulum and it made the sting worse
Day 2- Pinch was all but gone but urination was still weak- no pain- no weird colors or discharge
Day 3- Saw my doctor- he said urine was free from infection- prescribed 500mg of Doxycycline for Prostititus and referral for urology and said I seemed fine and he didn't think it was anything bad- but no physical exam of area though at this time- there was nothing physically different down there.
Day4- after 3 antibiotic pills over 2 days i noticed my groin was itching more than usual, but I shave it often and the hairs are halfway grown back and to be honest worrying about the itchiness made me itchy all over my body. Penis feel fine- I pee normally, I masturbate without pain....though my frenelum is still a little sore when rubbed
Day 5- I broke out with a red rash only on my bikini area- high up on groin between leg and testicle sac- both sides- looks bright red- smooth - no bumps pimples- no blisters- it's a straight line, right into both sides of my bikini line- urination is fine- penis and genitals look as the always do- no strange colors, markings, bumps- it looks and feels like jock itch - i've had jock itch before as I am a large man who sweats- I've also heard Doxcycline can make fungal infections sprout up which makes sense because if I go two days without a shower- I get it.

I've heard herpes can look and feel so many different ways so of course i'm worried but- Nothing around my genitals or penis - I feel completely fine physically now other than this rash on both sides. The only reason I'm concerned at this point is because of the events leading up to it- otherwise it looks and feels like a bad case of jock itch which I've had many time before.

Also to add to this- for nine months my tailbone is in pain- if I sit too long in same spot it kills- I work a desk job am and overwight
I am also a daily marijuana smoker
I am also a frequent masturbator- even if my penis is sore (specifically my frenelum) I masturbate through the sting

Anyone have an advice? I'm starting to think I had a inflamed my frenelum for overuse, thought it was penis tip, am taking antibiotics without any need and it caused my jock itch to flare up....I seriously doubt all my ailments are from the same thing.

Thank you...I thought it seemed like jock itch, because i had it before...but it gets a little scary when adding everything up ....I appreciate the advice...I've been hearing about tree oil and how it can really help.

I agree it is a yeast /fungal infection (jock itch) causing the new rash.  I would treat it with Lotrimin cream.  Wash socks and underwear in hot water and put baking soda in with the Tide (that you actually measured correctly - I have seen guys do laundry and you tend to skimp on the detergent).  You need to do this because feet and groin fungal infections get passed back and forth from stepping into underwear.  Do the same with sheets - wash in hot, but it's a separate load because it might not be truly infected like socks and underwear.

Use neem oil soap or tea tree oil soap in the shower to help concontrol the infection.

For the tip area, once you are done treating the area with Lotrimin cream, then use a little clear 100% aloe vera to the area.  And the sports underwear are good because they hold things in place to prevent chafing.  If you buy the right size they should be comfortable.
