There may be possible triggers within, please read with caution, I apologize for being so blunt but I tried to be courteous as I usually am.
Billions, I do quite well understand what you are talking about here. I wasn't raised strictly with a "religious" view of sex, but I was told that it was a sin to watch porn, masturbate, or have sex out of marriage. Thankfully I have grown up with a very healthy view of sex on my own terms, without listening to what others said.
I was 4 the first time I saw a girls private parts, she was 5, and we were good friends growing up till about 10 or so. She and I explored the sexual realms together, via her parents porn and each other.
My parents in no way had a good reason to tell me that sex was evil or bad, because they would have been hypocrites. My mom and father are divorced, I am a product of adultery, yes my mother thought she could take a year off from her twelve year marriage from my father. My father calls my mother a "porcupine" because she has been with so many men.
My father started letting me watch "T&A" movies when I was very young, my step-mom didn't like that but she didn't argue either. My mom had more men in and out of my life then Marilyn Monroe and Liz Taylor. Then there was my bio-dad, the sperm donor, when I met him at 9; he had a different woman in his bed every weekend.
Now with that being said did I feel shame sometimes with my masturbation, sure did, I thought it was sinful because of what I was being taught by my older brothers. Who both are extremely religious and believe sex is only for procreation, don't believe in birth control and yes they both have a lot of kids; however my oldest bro only has three, they were all C-sections. His wife had to have her tubes tied. So I am sure he is sexually frustrated, especially when his youngest is 16.
I have been with nine different woman since the age of 15, been married twice, for a total of about 10 years. I have only one child from my second marriage. I love every thing about woman, head to toe, no I don't have some weird fetish. By the way I am also bi, so that throws a whole new curve, because though I am not "religious", I do have a deep relationship with God.
I used to be ultra-conservative, but then I started using my God given brain and thinking for myself. I question everything. I don't like how man interprets things that probably weren't meant to be interpreted like the Bible and the US Constitution.
I am proud of my sexuality and glad that I have explored it. I don't particularly like porn that much but will I hit up a site, every so often if the mood strikes me. I really like reading erotica, it helps my imagination more.
I am so happy that I am with a friend that I connect with and we explore each other through Tantra. I see that I am rambling but this a topic that I think needs to be aired out, people are so repressed when it comes to their sexuality. Be it because of societal or religious repressive "norms".
Do I think that there should be better teaching of sex in school, yes, the US Military agrees. I was in basic back in the late 90's and that was just after the big Tail-hook scandal in the US Navy. They added one week to each basic training schedule for sensitivity training which included sex ed.
If we all had a healthy view of sex in the world we might just have fewer abortions, less STD's and a whole lot less welfare babies. Not saying that rape, incest and other things wouldn't still happen, because you can't stop pervs. However if little Johnny new how to "wrap before tap" it would cause less problems. Also this false notion that masturbation is some how bad, it is not, should you do it every waking hour; no.
Last thing and this little diatribe will be finished. My ex-fiance told me that most of the younger people in the town she lived in had HPV. She seemed quite proud some how of that and then proceeded to tell me she possibly had it; unfortunately I have no idea if there is a test for men. However I am not worried and neither is my sexual partner now; we both think my ex just said it to try to get a rise. Point being though, if we were protecting our children through a good education, things like this wouldn't be so scary.
Peace and love, everyone. If you have no one to love, love yourself.
