my girlfriend dont like have sex that much so she lets me have sex with her bestfriend is this a usual thing or should i be worried for n e reason? She used to like having sex a lot until her father died. y do u think she stopped liking it after he died?
Your girlfriend is depressed. She is too sad to want to have sex. She is too sad to care if you have sex with her girlfriend. It sounds like she is too sad to see that you are not being the kind of man she needs right now.
If you were any kind of man you would be able to stop having sex while she is going through this very difficult time. So either stop having sex with your girlfriend's best friend immediately or stop being your girlfriend's boyfriend. You can't be both.
