I am in a committed relationship and I have sex often, sometimes I will notice a somewhat aggravating (not so much painful, just annoying) burning or itching after sex. I usually attribute this to a lack of lubrication (I also get really itchy if I have sex soon after I shave, but that's always been razor burn). But my significant other has been out of town for 2 weeks and after masturbating with a dildo I felt a painful burning and slight swelling along the bottom part of the entrance to my vagina. Just trying to figure out what was happening I continued to feel around and right after masturbating inside of my vaginal canal burnt after I put pressure on it. An hour later the inside didn't hurt anymore, but the area around the entrance, my inner labia and my clitoris still felt uncomfortable and burnt after any touching. I have been always been prone to UTI's (I had one a few months ago that I didn't realize was there and ended up with abscesses on my kidneys from it). Apparently when I get UTI's they don't affect me like other people and I don't have any issues urinating. I also have extremely thick/creamy discharge every now and then. When I was the hospital for abscesses they told me that the extra discharge was from my body fighting off an infection. I had somewhat similar discharge a couple of weeks ago, but it didn't last so I pinned it on ovulation/my cycle. There is no pain/burning/itching without touching/stimulating. There is also no change in the appearance of my vagina, aka, bumps, sores, whatever. I can go to the doc and get antibiotics to for a UTI easily, I just haven't had the money lately, at this point I'm really just worried that I've contracted an STD (I was tested before I got in a committed relationship, but can you REALLY trust anyone?) Any help/info/advice/experience would be very much appreciated. Thanks in advance!
