Libido wanes when not in a relationship. When people are having regular sex in a relationship, their libido tends to stay consistent, notwithstanding other factors that can reduce libido.
You say that you’re all about affection. It sounds like your libido is directly connected to affection. As you’re currently single, you don’t have any affection. This is not something you can give to yourself or do on your own. I imagine your libido will increase when you’re in a relationship, because that’s how libido works, so I don’t think you need to be concerned about it affecting relationships, as the relationship should improve it.
There’s also lots of factors that can affect libido like fatigue, stress, etc. Sometimes people just go through phases also. Just like mood can fluctuate, libido can too. I imagine it will go back to normal soon, and will also improve when in a relationship.
