Only 28, soon to be 29 so there's quite a generational gap indeed. But while the idea of sex isn't taboo and it's everywhere the actual act of sex and talking about it in depth than just the broad idea seems to be. It's seen as something for adults only, anything involving sexual acts is labeled as R/18+ material. Even the idea of nudity is seen as inherently sexual so it's just kind of a thing I'm sick of, you know?
I'm also what is referred to as asexual these days; I view sex as 'meh' and I'd rather do something else to bond with my potential beloved like go out together or play video games or just hang out and be friends alongside the relationship.
RE: If your partner deprive you from sex for a particular period of time, which will you do, masturbate or have sex with someone else? And state your reason?
