Should i worry?

my husband started a new job as a bouncer, im really uncomfortable about him working in clubs and things, probally no need to say but because of other women and things, drunk etc i worry theyll hit on him, or :O flash him..lol and that he'll like it, am i silly to worry? i am quite insecure in our relationship, if its not normal to be worried about it, how can i work out my insecurities?
