Jeez the ignorance and misunderstanding about STD's with some people here is shocking.
Your ok because you have a piss after sex..... seriously?? With all due respect, if there is a virus or bacteria there, having a piss afterwards aint gonna do a bit of difference, once its there, its there.
As for her rubbing your cock against her pussy, hey, why dont you just fuck her bareback? Have you heard of herpes? Transmitted without sores present, from skin to skin contact, or unprotected oral sex? No cure.
Girls that offer CIM at higher risk of having a STD in the back of their throat While their throat will clear it in about 3 months, your cock wont.
As for the comment " CIM is rare, most women just spit it out anyway" - ummm, you already have cum in their mouth if they are going to spit it out so whats the difference, its in there, along with any virus/bacteria.
No offence chaps, but some of you really need to read more about the risks of STD's and in particular how easy they are to catch. Sorry if I sound a bit "mothering" and I agree that everything has a risk, but, knowing the pain it can cause and how easy it is transmitted, from experience, I was surprised how much I didn't know about them until it was too late.
My advice to you IK8133, if you are married, dont have OWO, dont let a prozzie rub her pussy against your cock and dont do anything without protection, because its not just your health your risking, but that of your innocent wife too, and some of these STDs can be more harmful to a woman than a man. If your marriage isnt good either talk about it with her, or move on and then start fucking prozzies and taking the risks, because that way you will only harm yourself.
By the way, your question, how did I catch it - yes, it was from a WG, a very classy one, with fantastic reviews, who was lovely, beautiful, but offered OWO and CIM which I took. About a week or so later I noticed a burning pain when I was peeing. Laid in the bath I then noticed white stuff coming out of my cock. My underwear I noticed after work had green/yellow goo in it and I had this horrific pain everytime I pissed. I also pain in my bollocks. Contacted her, she had a throat swob done, positive for Ghon.
Went to the GUM clinic who had to stick a swob into my cock which fucking hurt, then said it was Ghon. Had to then bend over a bed while the nurse put an intramuscular injection into my butt cheek with an anaesthetic as it was so painful, and that night I had to take 2 tablets the size of horse pills. It took another 3 - 4 days for the goo to stop oozing out of my cock and another week for the pain to disappear. Was all that worth it for a blow job - NO. Would I risk catching it again, knowing that you may be unfortunate enough to have an antibiotic resistant strain? NO. And I certainally wouldn't want to pass it on to someone else, it was bloody awful.
