Need Advice, newbie 19 yrs old

[Nyzz]

Hi guys, I just found out about this forum today, and I’ve been “attempting,” to do PE without any results. I’m currently 5.7 erect length, 3.2 flaccid. Im 19 and I just invested in a vaccum device (the ones that vaccum your tip with a sleeve so you can use it for ADS or whatever) and I also invested in DHT gel, since I hit puberty quite late, I’ve just recently started to develop facial hair, and I’ve been using dht gel on my penis which has accelerated that. (I’m of course using products not to lose my hairline of course.) I’ve been reading through the forum for new members, and I just wanted some advice on a stretching routine. I understand I first must do manual stretches, then keep it in that stretched position. However I can’t seem to find what a bundled stretch is? And I find it incredibly hard to stretch my penis past a certain length, my erect length. If possibly can anyone recommend a good stretching routine, and also when should I apply the dht gel alongside this? Thank you guys.
