Well I think there is some middle ground between celibacy outside marriage, and "group sex and no protection". There is nothing to stop one being selectively sexually active, and nothing to prevent one from having safe sex. I'm not aware of any diseases that aren't almost totally protected against by use of condoms etc. We each have to find what is comfortable for us - and certainly ignore anything resembling peer pressure on the subject. Hearing stories of (for example) your women seeing blowjobs as a status symbol in high school is just so sad. TV shows like Sex and the city are also not helpful (I think of it as 'Sluts and the city' personally - never in my life did I meet anyone of either gender who really has that many partners).

I think its quite possible to take your time and be sexually active at your own pace, without any hard and fast rules like 'no sex before marriage'. After all we can transfer and catch herpes by kissing, so to be realistic, abstinence on grounds of disease prevention would need to also include kissing - 25% of people have herpes and many do not even know it as it has never been symptomatic.
