A Glamour.com poll of 3600 readers found that a whopping 77 percent regret having a one-night stand, while 72 percent are sorry they dated at least one particular person in their 20s.

The magazine set out to discover how closely the popular TV series Girls in which 20-something women living in New York encounter a few hurdles as they work their way up in their careers, related to young women in real life and found that there were quite a few similarities.  

A shocking 61 percent of almost half the respondents admitted to having an abortion after having unprotected sex, while 12 percent admitted to contracting an sexually-transmitted disease after that night of wild abandon.

Around 32 percent said they felt ashamed that they had sex with someone while they were very drunk.

The TV show Girls is said to offer a more realistic account of what life is like for women in their 20s living in a big city than its predecessor Sex and the City, which had a far more glamorous imagining. Indicative of this more realistic approach is the fact that 18 percent of the respondents in the study admit they always thought they’d be having more sex in their 20s than they are having in reality.

But it isn’t only their sex lives that the 20-somethings regret. Around 55 percent say they wish they’d been more self-assured when it came to their career, with 44 percent wishing they’d managed to work out what kind of career they wanted, sooner.

Those party animals among the respondents admitted to trying to do their job drunk. In fact, being drunk was the source of 77 percent of the group admitting to risk their safety, while 75 percent said they’d done things drunk that they’d never do sober.

When it comes to finances, most have a lot to learn. Over 60 percent said they are racking up the debt, spending more than they earn, with almost 70 percent saying they feel pressure to be financially independent.

Just under half said they had no savings in the bank and 38 percent live off their overdraft every month.

Glamour magazine editor, Jo Elvin, remarked how similarly she behaved in her 20s. "It seems the fundamentals of being human don't really change."
