My girlfriend has many close male friends and i have many close female friends. She hangs out with them regularly and it doesn't bother me at all I trust her completely. But a few times she has slept over at the houses of a couple of men she has had sex with previous to me. When ever i try to explain to her that this bothers me she tells me that i'm to jealous and i don't trust her. is it wrong for me to feel bothered? is it wrong for me to ask her not to sleep at their houses? 

Edit: also, how should i make a the conversation more constructive with her?
Edit: they have also been best friends for years.
