Not exactly, they're instincts, it's the knee jerk reaction you'll want to go with, but you can figure out how to control it and do something else. Honestly, a lot of it comes second nature, and if you embrace it, it'll just come. But there's always a risk of easy prey.
Don't stay where your scent in strongest, try and mask it with things; other peoples clothes, detergent, food. Try to confuse their senses. If you can, you'd be good to find someone else that isn't tangled up with him. Lone wolves aren't always strong enough to fend of groups.
