Talking With Both Daughters and Sons About Sex
You will notice that this study which is mentioned below describes how sexual stereotypes influence how parents teach their kids about sex: daughters (girls) are encouraged to be abstinent and to delay sex, but not boys.
I see this same exact (sexist) pattern among Christian families: Christians buy into secular stereotypes that girls should be as sexually pure as the freshly driven snow and Christians wrongly assume females lack a libido, but males are assumed to be sex-starved horn-dogs who lack control, and boys are not generally expected to remain celibate.
Ergo, females are taught in Christian sermons and other Christian content to sexually abstain. Christian boys don’t generally receive as much pressure or sermonizing on abstaining. There may be something “off” about Christian teachings about sex, since they are mirroring secular cultural assumptions about gender and sex in these matters.
On the other hand, regarding other (non sexual) topics, I can see how Christians might BENEFIT (or, ironically, be MORE in line with the Bible) if they went along with secular mores instead of with their incorrect biblical interpretation of some topics. But on this issue, they sound quite similar to secular culture, and are off they mark, I believe.
