Can I do 3 days On and 1 Off this week?

I already practice PE for 3 months, I always did 2 days on and 1 off, and I wanted to know, can I do this week 3 days on and 1 off? My routine today is as follows:

8 minutes warm up.
5 minutes stretching (all directions 30 seconds hold).
10 minutes dry jelqing.
8 minutes warm down.
After 30 minutes off the session, I start kegel, holding 3 seconds for 50 times.

I just wanted to know, If this week I can do 3 days On and 1 Off, that’s because this week I resumed jelqing on Tuesday (as I always did 2 days on and 1 off, my day off would fall on Thursday, and I would resume my activities on Friday, but this week I will have sex with my girlfriend on Friday, and doing 3 days on and 1 off, Friday would be my rest day and I would use it for sex with my girlfriend), this week can I do this? There I would resume jelqing on saturday.

My measurements :
April, NBPEL : 15,2cm/6 inch——Girth:14,2cm/5,6 inch || BPEL : 6,7/17cm——Girth 14,2cm/5,6 inch.
July, NBPEL : 16,0cm/6,3 inch——Girth:14,7cm/5,8 inch || BPEL : 7,2/18,2cm——Girth 14,7cm/5,8 inch.

There is only one way to find out. Give it a try and if everything looks good, go with it. If you see signs of diminishing returns, go back to what you were doing.

But for just one time, I think you will be OK for sure.

Yes, it will only be this week, because my routine has become unregulated throughout the week ✌. What do you think about making the routine a little lighter on that third day just to avoid possible overtraining, or do I follow the normal routine anyway?

Yes you can. Your dick will probably not even notice the difference. Try it out a couple of weeks and watch your PI.
