I ask because I've known a guy for 4 months. We both like each other and things are getting more flirty. He is 3 years younger than me. I'm late 20s he is early 20s. Seems quite mature, he is already thinking for the future. We have so much in common.
People keep telling me not to go there because he's 3 years younger. What are people's opinions/experience on this?
