"Sexuality’s not the sort of thing where what worked for you when you were 14 is going to work when you’re 25 or 40," says Sarah Forbes-Robert, a worker-owner at Toronto co-operative sex shop Come As You Are. "It's a constant exploration of new ideas."

So if you feel like you're stuck in a rut when it comes to your sex life, you're not alone – or unusual. After all, with the pressures of a busy work and home life, who has time to research sex positions?

But if you're not putting effort in – and that goes for both of you – then you're doing yourself and your relationship a disservice, says Forbes-Robert. "You don’t want to keep doing the same thing over and over again – it’s not good for anybody," she says. "Trying new things – and using new muscle groups – are all very healthy for sexuality."
