I disagree.
More partners -> more experience + more learning about yourself -> knowing better what you need and want -> easier to find a suitable partner in a way that you know better what you need.
I for one have been with a few ladies already and I value serious relationships much more than one night stands.
I've been together with M'Lady (current) for more than a year.
Taking some time to calm down during a fight if getting angry/sad/whatever.
The other party might think that you are running away.
Make sure they know that you continue once calmed down.
