Strange thing on my clitoris

So idk what it is.I have it for about a year.It is on my clitoris and i looks like a pimple but not like acne,idk how to explain.It is like a very small bump.It doesn’t hurt.I don’t have strange discharges or itching.I went to my gyno a couple months ago.We did echograph and also medical test for infections and everything was fine.I asked her about that thing on my clitoris and she looked at it and told me that she doesn’t know what it is and if it grows to come again.(it doesn’t grow).I told her that i looked on the internet about it and she laughed and told me that she is sure that it is not what i’ve read on the internet.I assumed she talked about STD’s.I always have sex with my boyfriend with a condom.With my ex boyfriend was my first time(we only ,,did it” on my first time then we broke up) and he put his penis inside me just two times and then we stopped and then we broke up(it was without a condom).I talked with my boyfriend and he told me that i am just having health anxiety again(something regular for me) and that there is no way that i could have std+i have already talked with a gyno.Should i go again?Do you think i could have std?
