Does Sex Ruin Friendships?

Sex with a friend can change things. Sometimes, it brings people closer. Other times, it makes things awkward. It depends on the people and their feelings.

Emma and Jake were best friends. One night, they kissed and then had sex. After that, things felt different. They didn’t talk as much. Both felt unsure about their friendship.

Why Sex Can Ruin Friendships

Sex can complicate things. Here’s why:

1. Emotional Attachments

Sex releases oxytocin, the bonding hormone. One person might catch feelings while the other doesn’t.

If one wants more and the other doesn’t, it creates pain. The balance shifts, and suddenly, the friendship feels uneven.

2. Awkwardness

Things that once felt normal — hugging, sitting close, joking — can feel weird after sex.

You both know you’ve crossed a line, but you don’t know how to step back.

3. Jealousy and Expectations

What happens when one person starts dating someone else? Even if there was no commitment, it’s hard to see a friend move on when you’ve shared something intimate.

4. Fear of Rejection

If sex was a one-time thing, it might leave one person feeling rejected.
