I’m F27 and my boyfriend M28 we are in a serious relationship since 10 years and I’m committed to my best friend, he used to ask me about my fantasies and imaginations and I told him that I think about other boys and even his friends while masturbating

Idk how he didn’t get mad at me but was ok with me imagining other guys and even his friends Then now he put finger and thumb in my holes and sometimes help me to imagine gangbang , sometimes makes me feel like it’s threesome And he likes to fuck me in public, like in car he makes me half naked and fucks me Though people outside are unable to see But Is it normal? We’re in a super serious relationship and will get married soon
