Growing up in any milieu that says Sex is a Sin, at least generally, apart form in certain circumstances is bound ot affect your Sex life, and your whole life in various ways.
Had I exercised more sexual freedom as a teenager, because of what Society was at the time I would probably have ended up married to someone else than my wife of over 50 years anyway. Because i would have been shagging one of my previous girlfriends regularly, i would have felt obliged to marry one of them. Extricating yourself from a marriage is always painful.
So, although I wish I had not had the constraints of being a JW , or of Society in general at the time, my life may have been very different because of the " freedom".
But for JW kids today, when Society in general has become much more adult and sensible about Sex, the restrictions imposed by the Org cause too many to rush in to inappropriate marriages, which end up in heartache and pain, the kind that often goes on for the rest of the life of the people involved, even kids who have been born to the folks who never really should have married.
The Org causes unnecessary suffering once again by a 19th Century view of Sex.
