Clothes come off after one month.
A recent Durex report found almost a quarter of people globally would have sex with a new partner within a month. “In our culture, it’s a normal amount of time to wait,” says Phillip Hodson, sex therapist and author of How Perfect Is Your Partner?. “If you’ve been on four or five dates, the sexual tension has had time to grow. You’ve probably already shared a few kisses and cuddles and have a good idea about how suitable the guy is and whether you want to take the relationship further.”

Will it last?
Your love life will involve plenty of orgasms—and laughs. “After a month, you’ve built up the anticipation and shown awesome willpower,” says Allison. “You should be comfortable enough with your new partner to handle any unexpected mishaps in bed.” A word of caution: “People make less effort to get to know each other once they’ve slept together,” says Dubberley. “Don’t be lazy and substitute sex for communication.”

Clothes come off after three months.
“There’s a lot to be said for waiting three months before having sex,” says Gash. “By that point it’s not sex, it’s making love. You’re familiar with your partner’s strengths, weaknesses and flaws and you’re still keen to sleep with them.” Dubberley agrees that it’s time well spent: “The wait can be beautifully romantic.”

Will it last?
“Be careful not to lose the momentum,” says Gash. “After three months there’ll be expectations and the build-up can be better than the sex itself. Try not to expect too much—if you don’t assume the earth will move you, won’t be disappointed. First time sex with anyone can be awkward, however long you wait. On the plus side, if he’s prepared to wait three months it shows he’s not just in it for the sex, he’s more likely to want a longer-term relationship.”
