Thanks ladies thats actually really helpful!!
the sperm is still useful and softening your cervix so its not a lost cause. the orgasm is to get contractions in the uturus...try a vibrator, ive found it easier to have clitoral orgasms the last few weeks...and having an orgasm during sex wont necessarily start labour its more useful once your already in inactive labour and want to push yourself into active labour. good luck!
Maybe you can help yourself a bit :)
Probably because it is on the back of your mind that you need to . Mind you sex is not helping me.
