Masturbation As A Massage

Hi everybody, I’ve been doing PE (newbie routine) for 2 weeks so far (had some problems with erections and continuity while jelqing so I prefer to say that I took a test week) I used to be a heavy masturbator, like sometimes I would touch myself three times per day. After I read it was detrimental for PE I stopped, I also read that only cumming was bad for the workout, but not jerking off, so actually I’m just cumming once per week.

Having said that, the thing is I saw some comments about masturbation (not cumming) being used as a massage after PE, but no thread about it, the fact of not cumming as I used to is making me crazy, so the last three days I’ve been masturbating but not cumming for at least 1 hour per day.
Is this okay? Because if it is I could use this time to massage my penis after doing PE, and if it is not, do you think masturbating during the day (almost every day) without cumming is affecting my gains in a bad way?

Also, if any of you uses masturbation as a massage, how do you do it? Is there any specific technique or pressure to applied?. PE and not cumming are making my erections way harder and enduring, also my veins are getting more pumped at the moment and I think I’m doing good, haven’t seen any noticeable gains yet (I think my penis is a little bit longer and a little bit thicker in the mid shaft, but can’t tell if it is due to a better erection or actual growth) even though is too early to be sure, so I wouldn’t want to ruin that progress with masturbation.

Thank you in advance guys, I’m in fact actually enjoying PE, my goals are not so clear right now, I’m 6 inches in length and 4.6 in girth, I have a wonderful relationship and my girl says my dick is perfect but I’m doing this for me, I think 6.8 in length and 5.2 or 5.3 would be enough for me since I always make her cum sometimes in less than 20 min and others in 30, in her words I have a wonderful sexual performance, so I wouldn’t want to ruin that by injuring or damaging my unit even if it is not possible with masturbation, I’m really paranoid. Just to finish thank you to whoever answers.
