Behaviour expert reveals why you should be concerned if your partner has sudden ‘interest in having more sex’

Anyone who's attempted to navigate the sometimes more weird than wonderful world of relationships and dating will know it's chaos at the best of times and a total sh*tshow at the worst.

After finally making it through the perilous dating zone, dodging all the submarining, bread-crumbing, and even getting 'zombied' inevitabilities, there's nothing to say your partner will even stay faithful to you.

Oh yeah, and if that wasn't enough, there's also retroactive jealousy AKA 'Rebecca Syndrome', 'micro-cheating', and 'frozen images' to deal with on top of all of that.

Now, in an ideal world, no one would have trust issues, and everyone would choose the right partner for them but - as we all know by now - that can sometimes be the furthest thing from the case.

So, it seems only natural that people are equipping themselves with all the knowledge they need to project themselves when it comes to the world of romance.

To help shed some light on the matter, a behaviour expert has revealed why an 'interest in having more sex' from a partner could be a major warning sign.

Eldin Hasa, neuroscientist and host of the Human Experiment podcast, explained that 'changes of sexual behaviour' can be a major warning sign for possible infidelity.

Now, while common belief is that someone cheating would lose all interest in sex with their partner, as they are having it elsewhere with someone else, this can be far from the case.

The sexual desire of someone embroiled in a romantic affair outside of their marriage can actually go down or up.

Oh yeah, and another warning sign to be mindful of, they may also even be way more enthusiastic about trying out new techniques, positions, kinks, and sharing new preferences.

The expert explains that this happens 'because of the way infidelity disrupts oxytocin and vasopressin' which is 'typically released during intimate moments, fostering bonding and trust' and can alter 'the brain’s reward circuitry'.

"Alternatively, they may be trying to compensate and look less guilty by showing extra enthusiasm in the bedroom with you," Hasa told the Metro.

On the topic of dopamine, Hasa also warned that 'decreased emotional connection' should also sound alarm bells.

The expert says that infidelity 'disrupts the release of dopamine' - which is also known as the 'feel-good' hormone as it can produce a sense of pleasure.

This, in turn, results in a ;reduced emotional connection between partners'.

So, if you notice your S/O is being distant, avoiding emotional convos or just generally not supporting your emotional needs - it could be because their dopamine is going elsewhere...
