Can I use the phrase 'having/taking a shower' as a noun when it supposed to be present simple tense
Example:
I wake up then (I) having a shower
Examples that I found:
1 use less water when washing their hands, brushing their teeth, or taking a shower
2 Finishing a good movie, and then having to face the reality of your boring life
3 Let’s go dancing at the club tonight
3.1 Swimming in the ocean has been Sharon’s passion since she was five years old
4 Wearing loose pants while riding a bicycle is dangerous
5 So more eating, more drinking and more taking of photos - many of them painfully embarrassing
Question:
Can I use the phrase 'having a shower' instead of have a shower in present simple cases (I wake up then (I) having a shower)?
