You may have an uneasy mind which is putting a loads of thoughts about something is not right and I need to correct these and stress on you. Do the training, try to keep a good posture (not very hard), keep breathing ok and everything will be ok. Don't force into it.
Also, the main problem with swayback is tendency to ED which many times causes PreE. So it is not wise to ejac several times before sex.
