Nakakalungkot na sex is viewed as something casual nowadays

Me and my friends were drinking last night and napag-usapan namin yung about sa mga naging ka-fling nila, their experiences with one night stands, and their rather intimate moments with their exes. One by one nagkwentuhan about dun (like rotation). They know that I'm still a virgin, and when it came to me na, they proposed on hooking me up with a shs friend namin na nagkagusto raw sa akin before. They also are aware na kakagaling ko lang sa first break-up ko and sabi nila na babae lang din daw ang makakapagpawala nung sakit na nararamdaman ko. Then I told them na:

"Ayoko par, vinavalue ko ng mataas yung mga ganyang intimacy pre ayoko sana muna mabigay sa kung sino man"

then afterwards I told them na medyo traditional yung view ko about sex before marriage and stuff like that. Akala ko maiintindihan naman nila, but then they started telling me stuff like:

"Tangina pre babae ka ba?" "Ganda nung ex mo di mo man lang ginanito ganiyan, sayang naman" "Sayang tt mo pre di mo naman ginagamit" "Arte naman ampota HAHAHAHA"

But afterwards, we just carried on and minutes later change topic naman about college life and other shits.

I mean, I think for me it's not really a big deal na ganun, kasi nowadays I'm aware na mas open na ang mga tao when it comes to stuff like that, pero ewan ko. Nakakalungkot lang isipin na people are willing to just give away their virginity for a simple reason like that. I'll admit na I despise the hook-up culture na nagiging normal nalang in this generation. I think of chastity as something like the greatest gift that you can give to your future partner, and to see people just throwing it away for reasons like "Nalibugan ako pre" is really disappointing, to say the least.

tl;dr nagrant kasi napagtripan about sa trad view on intimacy (sex)

Edit: Thank you all sa mga insight. I'll stick to my principle. I've always had this line of thinking ever since I was fourteen. I always wanted my first kiss to be with someone I'll love for a long time, and now even my chastity. There were some people telling me to get off my high horse and stuff like that, but please understand na I do not view people who do casual sex as someone lesser than me, I just wish they valued their body a bit more.

That's all, thank you for the insights!!!
