(NSFW)How do you clear your mind? How do you stop thinking, analyzing, and worrying and just focus?

Some examples: You are used to having sex without a condom, but then when you start using them again (condoms); you can’t ‘get it up’ because the condom turns you off.

Or if you are ‘doing it’ and the sound of the rocking bed annoys you, and you ‘lose it’ mid-thrust.

These things are usually in out head, but how do you forget, focus, and just worry about ‘poundin’ it’?
