I ' m a semi regular used of a syn and a progasm . I tend to use the syn more frequently as it ' s easier to get in and as it is smaller it tends to move around more and give me a more enjoyable orgasm . The progasm fills me deeper and I can ' t use it for as long . I feel more deeply relaxed afterwards compared to the syn . I have had one experience where the the progasm pushed out precum and assume that it is was because the prostate was enlarged from stimulation with an aneros the day before or maybe my pelvic floor was too tight . I think that the after sensations come from the prostate stim and also an I iguales awakening associated with changes to your bodies nervous system through using aneros . Maybe go small for a while or try the progasm jr . what height are you ?
