I'm starting this thread to break the thought that a person's sexual past is none of the new person's business. First, I will say why I think it's a bad idea to keep one's sexual past a secret, then I will admit some possible points that it may be necessary or condoned. But let's face it folks, people fuck around, A LOT nowadays. Yes, there are lots of monogamous people and people who don't seek out sex unless it's with someone they care about (I fit into both these categories) but I'm finding that we are in the minority. So, most people end up having lots of sexual partners (and some people sicken me, when they start getting into insane numbers like the triple digits. Seriously, why?) And obviously, the more people you fuck, the higher the chance of STD's (or STI's as some want to change it to). Yes, there are condoms, but they can break, slip off, whatever. Now, your dick is exposed (or your pussy) to whatever the other person may have-and now you could be infected. And if you share yourself with lots of people, you have an incredibly high chance to spread the disease further. Now, I'm not on here to advocate monogamy, but this IS one of the benefits. Also, if you are going to have sex with someone, you need to be able to trust the other person. Does your partner need to know details? Maybe not, but if you've been around the block, or country, who you are having sex with deserves to know. If you are going to be intimate enough with a person to share your body with them then you can be intimate enough to open up to that fact. Now, I will concede that sometimes people just want to know out of insecurity. This could end up being a whole different thread, the way things work here. Yes, a person's past is their past, but it is NOT just harmless fun, you cannot rationalize it that way. There are too many sexual diseases out there, and lets not forget the fact that it creates new human life. And yes people can lie, but if you are going to lie about having an STD, then you need your head checked. I'm not saying to go around telling the world who you've slept with, but no one has the right or the excuse to say (if someone asks you) "it's none of your business". If it's none of their business, then you don't have any business having sex with them.
