should I feel bad?

i was planning on meeting this guy (for sex) and he asked me when was the last time I had sex and I said “last weekend” and he said “ew wtf” and I was super confused and he said “i bet you’ve had sex with every guy in the city” and I just got super upset and blocked him. the question is: is it bad that i’m sexually active at 17. ive had sex with 14 guys and this is the first time I feel bad about it
