No never thought of hollies (re your comment below) but great song and sound, way better than mine of course. But it goes like this when writing and its why few people write good lyrics, because it is a ton of work and effort and the majority of people  are not dedicated enough. They throw words on paper and that is a lyric sheet.

A solid writer says-i want to evoke an image here in this chorus of pleasure (myself) like that feeling of toes curling, monkey face, climax, ecstasy, but i want to be classy and not crude.

Words and ideas that fit this ethereal feeling-fairground, roller coaster, flying high, carnival, carousel, elation, drug ideas etc. Then you start to paly with the idea and synonyms for these words etc.

You have to consider ideas that are coming after this and rhyme scheme. I wanted next lien to ryhme and had the idea that the partner that left him or her might have said sarcastically well you wank yourself so much you don't need me anyway.

That led me to the line, I know you said i do oo it well. 

Looking back above then i see carousel rhymes with well. one rides on a carousel and one sometimes thinks sex is akin to a ride.

So i start playing around with and adjusting for rhytum and meter-

tonight i'm gonna pleasure myself

like riding on a carousel

i know you said i do oo it well

I'm gonna pleasure myself

seems crazy simple and it is as written out. but evoking the image i wanted with meter rhyme phrasing and such takes some time.

but worth it in the end as my songs when i complete them successfully and put in the work serve to literally pleasure myself!
