Hello everyone, i have a question, im so confused :(

what would you do or say if your husband ask you to get a sexual massage from another men?? Would you do it?? Do you think is normal??

He's been my only one, we're been together for 13 years, i wasn't his only one obviously., and he's telling me to try new things but i think this is over my limit because i dont have experience in sex i don't know what to say, think or do.

I talked to him yesterday that im not letting any man to touch me and he got really upset. What do you guys think??

Im over reacting??
