Am I being insecure about things??

My boyfriend always wanted to do modeling and I mean why not? He's a very good looking guy! He's been doing shoots with different photographers for awhile but now the photographer wants him to do a shoot with a girl. I looked at the shoots this guy does with guy and girls and the girls are in bras and underwear and the guys are in boxers. I'm happy that he's getting these opportunities but I really don't want him to do a shoot with another girl wearing almost no clothes. Am I being insecure or would you guys be ok with your fellas doing this? Thank you! :)
