A lot of what makes sex fun is exploring and playing. “The idea of consistently wanting exactly the same type of sex as your partner might ostensibly seem perfect, but as well as being improbable, in the long term it could even get boring. Examining sexual divisions offers unique opportunities for personal development and revelatory discoveries,” says Moyle.

This might seem trite, especially if you’re in a relationship where sexual issues have run on so long and the damage has ploughed so deep that your soul feels sandpapered raw, but it is at least worth heading into the process with a positive head on.

Comedian Fran Bushe’s show Ad Libido centres on her struggle with vaginismus: a condition whereby the vaginal muscles involuntarily clamp shut. “I have to do extensive admin with partners to actively build up our sexual compatibility because of how my body functions,” Bushe says, “but it means we create something special together; they’re not just whipping out the same toolkit of moves that worked on their ex.”

Acknowledge the awkward

Therapeutic exercises can feel excruciatingly contrived when you first attempt them. Many have a tree-huggy vibe that makes you cringe. “Recognising how silly and vulnerable you feel out loud helps break the tension, and laughing about it together is bonding,” says psychosexual therapist Sarah Berry. Studiously pretending that embarrassment doesn’t exist is a form of performance, when your real goal should be to share authentic, honest experiences.

“You start by touching each other while still fully clothed, avoiding erogenous zones, then gradually build up intensity over a series of weeks, to help you tune into sensations and emotions,” he explains. “We both felt like dicks, but by week four, my dick worked. Removing expectations I had to get it up helped, but so too did giggling at the ridiculousness. For months our bedroom had been the site of tearful rows.”

Think about why you have sex

“A 2007 paper published by The University of Texas at Austin identified 237 different motivations subjects gave for having sex, from ‘to show thanks for something my partner has done’ to ‘it gets rid of a headache’ to ‘it makes me feel closer to God’,” says Jennifer Gunsaullus, the host of Dr Jenn’s Den, a sex education show on YouTube. “Examining the true reasons we’re seeking sex in each instance – like relief from boredom or stress, or for a self-esteem boost – can highlight where alternative actions may still satisfy our needs.”

Schedule sensuality

Setting out a schedule for sex has a bad rep; it seems clinical and unromantic for lovemaking not to spontaneously spring from burning desire. Yet setting aside predetermined windows for eroticism shows that it’s a priority, and is a damn sight better than leaving things to wither indefinitely on the backburner while life gets in the way.

Plus, knowing when to expect intimacy saves higher-libido partners from the fear their ad hoc come-ons might be crushingly rejected or interpreted as hectoring. It also allows lower libido partners to build parship dating site the anticipation and get their head in the right place for jumping into bed

“Make sex menus: brainstormed lists of all the sensual and thrilling things you know you like or would be up for trying, and see where you and your partner overlap,” suggests Barker. Download DIY guides from megjohnandjustin.
