Is this a genital wart or a skin tag.

I recently received oral sex from a women who afterwards told me that about 3 years ago she had been diagnosed with hpv/genital warts. Two days later I noticed a small bump on my inner thigh/groin fold area. It doesn't really look like the pictures I've seen online and also to note I wear boxer briefs that I have noticed fit rather snug in this area and have been chafing pretty bad on my right inner thigh as it is getting warmer. We haven't had andy genital-genital skin contact. I am a kinda nervous about all this and just want to get some sort of peace of mind if possible. It has been just over a week since our encounter and I've noticed the bump looks to have gotten smaller. It also looks like their may be a hair coming out of the side of it but it's hard to tell. Any help that can be offered would be great.
