Age Gaps

Ali
Hey y'all. Advice time. I'm 18, have only been in one relationship, am a virgin, and have never really "dated" before. I met a guy today who seems cool, but he's 26 and doesn't know I'm 18. Should I keep flirting and go on a date or two, and let him know how big the age gap is & see where that goes or just don't even bother? :(
