Since the terrible old days of being abused (and, I'm so sorry for this happening to you), have you had sexual partners? If so, would you be on the kind of terms with them that it would be easy to ask them if they have genital warts? If you have had partners but aren't in that kind of easy, relaxed communication pattern with them any more, you do need to go to the doc. Ask for a woman ob/gyn, and explain that you are super uncomfortable about gyn exams because you are a survivor of sexual abuse. Ask if they can prescribe one Valium for you to take before the exam. (If it is not a problem for you to take.) One other thing that eases the fear and triggering feeling, but it kind of silly (actually, it works because it *is* kind of silly) is to take a party blower with you, the kind that roll up when you aren't blowing on them and make a phooo! noise and roll out straight when you are blowing on them, and give a good blow when the speculum goes in. (Warn the doctor. lol) You can even hand one to the nurse and ask her to do the same. It really sounds dumb, and it is, but because it makes everyone in the room laugh (especially you) and because it gives you the momentary illusion of some kind of control, it works to relax you. We got my son past his fear of shots that way -- Mommy, Daddy and he (plus the nurse) all blew at once when the shot went in, and we were laughing and other nurses were coming in to see what the heck was happening. We did that for several doctor visits, and now all he has to do is blow air out gently when getting a shot. (It still feels like a shot, but it's over in a moment, and he is not distressed.)
Anyway, good luck, do get checked. If it is an STD, you definitely want to know.
I do think our skin isn't always 'smooth' there. Is this a change from how it was before or you just noticed it? A doctor should be able to give you a pretty clear answer relatively easily. Women usually have a gynecological exam called a 'pap smear' every year. Have you had one of those yet? I know after being abused this is probably not something you want to do but it's really important. Doctors are clinical and an ob/gyn is very efficient at getting it done quickly and easily. Is this something you could do? At that time, they can look to see if it is a wart, just the way your skin is or if something else is going on. I just try to think about something else during the exams. You could try headphones and your phone with music. That might work and doesn't have any last effect after the exam.
Here is information on genital warts. https://www.mayoclinic.org/diseases-conditions/genital-warts/symptoms-causes/syc-20355234. Now, I don't know how old you are and if you had regular doctors visits. But for the past several years, doctors have been vaccinating against warts starting in the early teens. I have a 14 and 15 year old sons and both have had their HPV vaccination. So, maybe you were vaccinated.
And this really could just be normal lumps and bumps of that anatomy. Let us know!
