Long story: sexual tension between exes

My ex and I broke up six months ago. We didn't speak or see each other for five months until last month when we found out a common friend of ours was going out of the country for a while—this caused for our group to have an impromptu reunion.

For a month since then, we've been speaking every day and seeing each other every weekend. Eventually, things got confusing... We found ourselves in this "honeymoon phase", and we were back to enjoying each other's company.

Last night during a sleepover, things got a bit too intense and touchy. We acknowledged that we both have this unresolved sexual tension going on but that even if we acted on it, it won't really mean that we'd get back together. We agreed that it's not yet the right time since we might rush into things and eventually ruin our friendship and whatever chances we did have in getting back together.

Just a bit of a background: we've been friends for yeaaars before getting into a relationship with each other. That's why bouncing back to being friends was quite easy. We both don't want to ruin our second chance at friendship and/or relationship (if ever), so we're keeping a level head.

Or so we thought.

We made out last night. We're not particularly awkward about it with each other right now, but of course I can't help but think if what we did was okay... Is this normal? Having leftover and sexual feelings over your ex even when you know you can't sort things out too seriously yet as a committed couple? I feel weird. Not sure if this is hormones or real feelings.

Lol, probably not the first time this has happened to a couple, but it's the first time for me. Which is probably why I'm rambling.

Thanks for reading this!!!
