Is your libido waves or more or less constant?

I've noticed that many people have life periods with very low or very high lust-factor and interest to kinky activities. While others are more or less constant.

In my life, there was months when ropes didn't have time to rest between sessions, while sometimes these was many months in line when ropes are even not remembered. Sometimes it is possibility dependent while most of the time it is just a matter of mood.

Personally, i am not 100% comfortable with that, because sometimes waves didn't match, and sometimes it is just multiplies doubts in already very complex relationship.

How about you? Are you comfortable with yours condition?
