Yes, today, your first time intercourse is a big deal in a lot of cultures.
for sure though, have sex with a person you truly trust and love very much. but, i've got to say, try not to give into pressure. just because a lot of people you know are not virgins doesn't mean you should have sex because everyone else is doing it. plus it may seem like everyone is having sex, but trust me, not everyone is. there are a lot of girls who are proud of being virgins, and being a virgin is a true gift. giving it away is a bigger deal than you think. plus if you don't want people to pressure you don't tell them your a virgin anyways. and if they ask just say something like: "i'm not really concerned about what everyone else is doing."
just because you don't have sex for a long time doesn't mean you'll be a 40 year old virgin like your boyfriend said. he just wants you to give into him, and make him happy. and a lot of people don't lose their virginity when their drunk either. some people are just smart about their decisions and know what's best for themselves.
all you need to do is: 1. make sure your first time is with someone you love, know very well, and trust. not some stranger you met at a party or something. 2. use protection always, like condoms or birth control so you won't end up making regrets when your pregnant. and 3. make sure your emotionally ready. your virginity is the most Precious thing you can give to a man. smart people's first times are special, and pressured people usually don't turn out well.
be the smart one!
