I don't know but I am also in that case. 我 try 了一年都唔得, 個人幾 down 又緊張, 之後, 小X 咗半年內 竟bingo.
I think 我冧住冇咁快得, 個人輕鬆d 掛, 而我又驗過 everything is normal (including doing pelvic ultrasound and 照輸卵管睇下有冇塞), nothing is important than relax, 勤力小小 do do and after do, 墊高小小你個 pat pat and wait for a while before going to toilet
