but if it does not work after the test drive, your first time will be gone.

Plus, test drive what? you can tell by other behaviors related to sex, instead of intercourse, which is more dangerous.

认真跟bf谈一次吧。

我自己的case，我和bf都不小了，在一起也几年了，感情很好，但是我也不是很热衷于结婚他也经常问我，我也经常说“怎么又谈这个”但我本身绝无骑驴找马的想法，只是没有ready而已，毕竟是人生大事嘛。其实我觉得感情好就好，一纸婚书完全只是形式而已。我觉得一辈子在一起不结婚也很酷啊，不过实际情况可能还是不允许，因为结了婚貌似financially有好处，我又是个比较俗的穷人所以mm要搞清楚你bf的想法，看看到底问题在哪里。如果他真的对这份感情不认真的话，还不如早点退

But before he met me, he had sex with a few other girls. Even if he has no disease, even if using condom, we can not make sure it is safe. What if some bad things happened, who will be responsible for this. I've also heard it is very easy to get female problems if you have sex too often, or not in a correct way, or non-clean sex, which we can not be 100% sure.

I just don't know how people can treat sex so casual. After all, it is directly related to your health.
