How "flirty" are girls to amerian sailors?

My husband is in the Navy and was just deployed.I would just like to say I don't think he will cheat, I trust him ,BUT I am concerned about other girls flirting/trying to hook up with him. I'm usually not the jealous type, but since Ive gotten married I will cut a ***** lol But in all seriousness, I will admit that it bothers me not knowing everything that they do while he's in port, only because we do have awesome communication and now we don't because of him being away. I do not want to be the overbearing wife who has to know what her husband is up to 100% of the time, that's crazy and I don't want to be the wife that tells him he cant go to the bars and cant talk to woman, but some girls don't care and will try to be promiscuous.So I just want to know if anyone has any experience with this.
