I'm 19 and I've recently started seeing a 35 year old man. Is this a problem?

We've hung out a few times. Never had sex or kissed we've just been friends. I've had feelings for him since the beginning but never told him and he just now told me he has an attraction for me so our feelings are mutual. Should I just go for it? I don't really see any reason not to, but he has two sons I don't know their age but one of them looks like he just started puberty. What do you ladies think? 🙄
