I am a bit baffled by the phrase "sexual safety". Not trying to be provocative there Kirsten, but I think simply saying "safety" would have been enough.
Busking is potentially dangerous anyway. If you intend to do it well, the first thing you have to do in a show is to gain attention. It does not always come in the forms which you wish it to. Your show can attract the attention of your audience, but it can also attract the bossy shop owner, an aggressive drunk or just your common or garden bully, who likes to feel superior to someone else.
As travelling and being in strange places is an integral part of the job, yes it can be dangerous. For instance, I could imagine that a woman needs to me more careful than a man about accepting invitations or selecting a place to sleep in general.
I was fairly strict about several things when I was doing it full time (up to a couple of years ago). For instance, I would not drink alcohol if I was going to sleep alone in my bus at night. (I never drink when working). It was different when I was parked next to other buskers. (Assaulting one busker among his or her friends is an effective way to commit suicide). I disposed of money quickly and I was very careful about getting my instruments and equipment to a safe, secure place after a show before partying - if I was going to party. It was also important to be strict about eating properly. Especially in summer, you can dehydrate quickly if you don't - no matter how much you drink.
Safety is important if you want to stay in the game for any length of time. I can appreciate that there are some differences for female buskers. Let's face it though, there are some differences in the needs of men and women in plenty of other professions too. In that respect, I don't think that busking is so different. I am interested in your comments though, Kirsten and in seeing how the discussion develops.
