Am i being too jealous with my girlfriend?

She has a lot of guy friends and she hugs them and all, but i accept that. I expect her to be fine if i hug a girl i know. But she is good friends with one of my best friends. They hug and she kisses him on the cheek and says "I lover you peter" in a playfull way when saying goodbye and she was telling me about a "Hilarious conversation they had when they were texting once. She was talking about her boobs for some reason and she said "Arent my boobs good enough for you peter?" and he said "No id totally motorboat those badboys" . Another time she jokingly text him saying "When are we going to have kids peter?" and he said he would donate some semen to her i na cup and she said she doesnt have a turkey baster to get it in there to which he replied "Sex it is then". These are all in texts she told me about. Am i wrong to assume this is inappropriate and disrespectfull to me?
