Premature ejaculation & not lasting erection

Hi,
I am 53 years old
94 kilos
1.75 m. Height
Try to eat a balance meal, but too much
Non diabetic
Good blood pressure
Good relationship with family and friends
At the beginning good erection, semi hard, not long lasting
High sex desire, will go away after ejaculation
high cholesterol (but now trying to reduce it), eat too much before I get to sleep, I feel happy, have desire to do my hobbies but then goes away, don't excersize, my job is in the office seating all day.
Since 11 years old I masturbate like every 3 days, then when I got a girlfriend only intercourse, but I always suffered from premature ejaculation in the first intercourse and in the next hour the second intercourse I lasted more adequate, I use to ejaculate 2 times in a session, then later in my 20 to 45 years I start to control the ejaculation till 1 hour
But now I have a lot of desire like every 3 days, in the beginning I have very good erection but I have a lot of desire to ejaculate early I can't control it and if I stop my erection goes down and then it gets difficult to get an erection again, and if I get it I have to come because my erection will go down.
Now on a sex session I only ejaculate one time and all the sex desire goes away, there's no 2nd or 3rd ejaculation.
Basically I have good sex desire, have a good erection on the beginning but then a weak erection and premature ejaculation
I like to see porn movies and masturbate but I control my ejaculation
I drink coffee each day it relaxes me, what can I drink as a substitute?
I get medicine in drops
Need your help!!!!
Thank you
