1-Kulang kasi ang kultura ng Pilipino sa socialization education. Ung mga batang 80's at 90's kusa nila yan natututunan sa community dahil mas malaya sila nakakalabas ng bahay at nakakatambay. Pero ung mga magulang ng mga bata from late 90's to 2000's mejo overprotective. This robs their children with important learning resource not found in school (professional setting).
2-if first generation middle class ang parents mo, likely na tinuruan k nila to focus on studies and neglect relationships sa paniniwala na pag may pera ka, you will be fine in social terms. While at the same time ang popular culture ay baliktad ang turo. Di baleng hindi mayaman, basta attractive ang itsura at ugali. To appeal to both beliefs, people will rather look for the one who is both may pera tapos attractive pa, up to a point na wala na silang choice kung sino man ang available. Leaving you waiting for "love" feom someone na wala nang choice.
3- it is likely na ang religion mo ay nagrereject sa casual sexual encounters as a basic human need, at tinatanim sa isip mo na ang mga action na ito ay strictly for procreation reasons. Tapos nagcoconflict ang mga nararamdaman mo sa beliefs mo. While 21 is too young to have a spouse, it is a bit too late to just begin learning the dynamics of building a balanced and healthy seggs-life. Everyone else is just like you, trained to keep seggs as a taboo matter, kaya mahirap maghanap ng setting kung saan freely mo ito macocommunicate.
