WELCOME! to the Forums.
You probably won't receive any more harassment than you would in your local neighborhood rides. There are stupid guys everywhere who make gestures, insinuations etc. If you are not intimidated by these lewd characters in familiar surroundings, then it shouldn't be a problem elsewhere.
I've known several women who have solo-toured with no bad experiences. There are several other women, here on the Forums, who are planning solo trips. Perhaps they'll come on and give you their views on the subject.
The point is, don't allow others, who have no experience of solo touring, turn you off to a wonderful adventure. Good Luck.
