It is a little into a month and I haven't seen too much into the gaining of random erections, I know my dick is much harder whenever I am with my girl and I can feel it growing hard. However, during sex I lasted just as long as I usually do and the refractory period was still longer than I would like. A few weeks left and my 2 month supplement test will be complete! So far it Is not too great on the random erection prolonged sexual pleasure aspect, but yes my erections are harder when aroused.
