Want to have great sex with your partner? Well, then wait for four years.
That's the conclusion of a new survey which revealed that couples enjoy the best sex of their lives when they have been together for four years.
Lovers believed that, that was the point at which they felt comfortable enough to lose their inhibitions, the poll of 3,000 found.
One in four of total polled admitted they were more confident with their body after a few years together, The Sun reported.
While 60 per cent felt more able to try new things, surprisingly, only one in ten said sex improved after marriage.
A spokesman for Philips, who carried out the survey, said: "Sex is like any other part of a relationship - it grows and develops in time."
