Almost every guy I know, including myself, would prefer a virgin. The so-called expert sounds like an immoral piece of garbage. Sorry, thats my opinion.
From reading Torah, I find girls who are virgins before marriage rather than those who sleep around and open up their legs to several different men are the ones who are more respected and honored.
Don't forget doctors make a cut of the profits from selling you birth control pills. So much of the medical and pharm industry is ruled by corruption and greed.
Birth control pills are also highly toxic, destroying our water/fish supply and are responsible in hormone imbalances in women, as well as increases in various types of cancers. Trying to control your body in a way Hashem did not intend, has consequences.
