||How is the transition from shy, retiring, damned-if-i-let-you-touch-me virgin to adult sexual human being supposed to go? Speaking for the both of us who picked catholic morality. If it makes any difference I'm middle-aged already and still can't figger it out.
Generally, you meet a guy, through your parish, or pehaps on the internet, and decide that you enjoy his company, and also a part of you feels physically attracted to him. This is scary, because said guy may not have reciprocal feelings, but like diving off the high diving board, you just have to do it, express your interest. Remember, faint heart ne'er won fair man.
If the interest is returned, you proceed to displays of physical affection, then engagement, then posting banns, then getting married, then sex. If the interest is not returned, it's back to square one, looking for another compatible guy.
All in all, a very daunting task, opening up oneself to damage one's self esteem, particularly after being rejected deeper and deeper into the cycle, as increasing physical intimacy leads to increasing emotional intimacy, and repeated failed relationships can lead to damaged emotional growth.
So, no magic bullet, just lots of potential for hurt, but the rewards are great.
