@Elcief_SSN Not really a Japanese thing but more of a teenager mentality. The idea of being "inexperienced" is usually something someone young considers embarrassing, even though they're probably the only one thinking it.
@burningknuckle We sorta have this expectation that our teenager protagonists are going to be ready to marry our fmc, until we remember they're also horny teenagers. However it's a manga so first girl wins aye?
