Is it normal to share your girlfriend?
Depends.It depends
It can be normal if everyone involved freely agrees and feels good about it. If your girlfriend isn’t on board, it isn’t sharing—it’s a breach of trust.
Some couples choose an open relationship or another consensual non-monogamous arrangement, and others prefer exclusivity. Neither setup is automatically better; what matters is that everyone involved is an adult, knows what’s happening, and genuinely agrees without pressure.
Talk openly about what “sharing” means to each of you—boundaries, safer sex, and what happens if someone changes their mind. If one of you is only agreeing to avoid losing the relationship, that’s a sign to slow down and talk more.
