Innocence can be referred to as a state of unknowing, where one's experience is lesser, in either a relative view to social peers, or by an absolute comparison to more common normative scale. Sometimes we hold ourselves in high esteem, the morale of our dignity is well magnified, that we are afraid of a tainted image.
We tend to analyze our values and self-dignity in comparison to what could defile the morale and quality of well-being we have set aside. We seem not to have control on some emotions that comes along at some point, not because we are empowered, nor overwhelmed by the state we are subjected to, but we seem to be weak in the spirit. The self-controlling energy that seems to go by the values and norms we have set aside seems to be weakened by the emotions. In addition, this seems to happen by the state of the mind not being on the same par with our body, some external burden, which seems to be greater than what we can bear at that moment seems to be working in place. Together we tend to go down the trail of disappointment, which subsequent result after we get together with the state of our well-being; we realized we have lost our innocence.
Infatuation and Lust plays a major role in the defilement of our sexual well-being. I tend to hold myself in high-esteem, no sexual intercourse with a complete stranger, on internet hook-ups. Being a reclusive state and not really interacting with people, tend to work with boredom and loneliness, which wont probably have a good effect on a sexually active young male. When the mind is tramped with such feelings and you just want to relieve yourself of the sexual tension (when celibacy is not in place), the next available option will sure be taken on, the experience might worth it, and it might not, but when you reconcile with your body and spirit, you tend to realize the self-esteem is being diminished.
My normal reaction is to start treading on the path of regret, only if its that bad and I couldn’t just take the thought of disappointment away from when I remember what happened, worse scenario when I cant believe that can happen to me in any situation. The subsequent feelings will probably take its toll on me. Getting the realization that some things have to happen, there has to be an adventure for a hale and hearty young man, but we want to relate with something we are proud of, but something we are probably ashamed of will sure show up. Trying to learn from the mistake seems to be the next option for me and I will probably try to check what’s to do and make sure I dont fall down that pit anymore, because it wont build up the dignity, with time it might but the experience will surely haunt you only if you let it.
Its my past I have to let go. Its easier to let go provided the circumstance fits well with your persona but what happened seems to just be right on your classification of defilement. Most times you really cant help the feelings, cant just help what happened, forget the past because you cant change it. That’s you, that’s what makes you unique, hopefully the situation wont just haunt you still..

Well, we cant change our past, we just need to reconcile with ourselves and make sure falling into that same ditch doesnt seem possible anymore. Dont let out all secret about you to your prospective partner. Live life as is, and have fun!!!
