Just like my girlfriend and I, although we discussed this topic in college, we never tried it, because I am a conservative person and my girlfriend is also a conservative person. We think this should happen after marriage, not in college, so even if we know it, we have never tried it. Like one of my roommates, he is a typical love rat. He and his girlfriend tried this kind of thing when they were in college, which caused his girlfriend's stomach to get bigger in her senior year. At this time, he was also afraid that several of us would chip in and choose abortion. Therefore, I think we must be cautious in dealing with this kind of thing and maintain a responsible attitude. If you don't decide to be responsible in summer, I don't think we should try such a thing too early. So I think both boys and girls should be cautious and better in this respect.
To sum up, I think my views on this topic during my college years are actually correct and objective. I hope all students can take this matter seriously at this age.
