Will semen and lots of walking help me efface and dilate?

And help the baby drop?

Sex in the last month of pregnancy may encourage cervical dilation. Sperm contains prostaglandins that may help thin the cervix.

not sure about the baby dropping though.

Sex and walking are supposed to encourage dialation and effacement but does not mean it will. I am 38 weeks and walk constantly as I have 2 other children and have plenty of sex and am only 2cm... no change been like that for weeks.

it might, it might not..... i was taking evening primrose oil capsules and drinking raspberry leaf tea from 32 weeks and was having lots of sex and walking baby had dropped by 32 weeks anyway was dilated to a 2 by 36 weeks but was only 3cm by 39 weeks(the day i had him) and nothing helps the baby drop. baby will come when ready.
