Thinking about somebody other than your partner is more common than you'd think.
Nearly 67 percent of men acknowledge that their partner might have sexual fantasies about other people, compared to 74 percent of women, one survey by Superdrug Online Doctor found.
And if you're someone who has thought about (or frequently thinks about) someone else while doing the deed, it doesn't necessarily mean that your relationship is doomed.
In fact, four in five fantasizers rated themselves as either satisfied or very satisfied with their companions.

However, it was found that more non-fantaisers were satisfied in their relationships. 60 percent of these people said they were 'very satisfied' in their relationships, while only 35.4 percent of those who admitted to fantasising about others put themselves in this category.
I mean, I can't say I'd personally love the idea of my significant other thinking about someone else while being intimate with me...

According to sex consultant Julia Stein, there are six signs that your partner is thinking about someone else during sex.
Avoiding eye contact
According to Stein, eye contact is 'one of the most powerful tools for staying present with your partner'.
"When someone consistently looks away or keeps their eyes shut, they might be visualising a different scenario or person," Stein told Cosmopolitan.
She added: "If they specifically avoid eye contact during moments that used to feel most intimate, that’s particularly significant."
Seeming emotionally distant
"When the emotional warmth disappears, it often means their thoughts are focused somewhere else," she shared.
After sex could be a key indicator that someone has 'checked out'. Stein said: "You might notice they don’t initiate affection afterwards. That means no cuddling, no pillow talk, just a quick retreat."

Making unusual requests
If your partner all of a sudden wants to try something very specific without any discussion with you beforehand, this could be a sign that they want to 'mirror what they’re imagining with another person'.
New interests can be healthy though, says Stein. "If someone gradually explores new interests through conversation and mutual discovery, that’s healthy growth," she explained. "But if they suddenly demand something specific with urgency or insistence, it suggests they’ve been thinking about it extensively, possibly in the context of someone else."
A change in bedroom energy
Inconsistency in your sexual partner's energy levels is a key tell that they have something else on their mind.
Stein shared: "They might seem disconnected one moment and overly intense the next, as though they’re trying to compensate for something."
She added: "Sometimes partners become more aggressive or distant as a way of separating the physical act from emotional connection. They might be using the encounter to play out a fantasy rather than connect with you."

Repeating 'scripts'
Somebody might appear as if they're following an imaginary script instead of naturally responding in the moment with you, signalling that they're 'working through a particular fantasy'.
"It’s like they’re following a script that exists in their imagination rather than responding naturally to the moment you’re sharing," Stein said of this.
Rushing through sex
Every couple has a 'quickie' sometimes, but it could be a red flag if all your sexual encounters feels that way, says Stein.
She insisted: "A partner who’s mentally present typically wants to linger in the moment, not escape it as quickly as possible."
