Well I can almost relate to this, my ex hated me going out with my friends even though it wasn't very often. Yes I did have female friends but I never flirted with them or anything like that. Yet she went mad if I talked to one of them and would text me every two minutes demanding to know where I am and who I am with (this was even if I went down the road to the shop), but yet she had male mates and talked to them and she went out. So I sense a bit of double standards here.
You two need to talk about this like now not later, and tell him how you feel about his jealousy because if this goes on then this relationship will not last, and the fact he said he may not control himself with his ex spells bad news he can't have one rule for you and one rule for himself, i'm not even sure a talk will be enough to save it to be honest though especially if he does not listen then I would consider dumping him. You both need to trust each other if you want this to work.
Also at the end of the day you got to have a life outside your relationship you can't let him stop you going out and stuff, you have to have your own space at some point, if he loves you he will understand that.
Seriously jealousy is no fun and it will ruin your own self-esteem.
