Just make sure you lay down for a while after he finishes in you. Like lay on ur back with ur hips angled up if possible for like 30 min
any of them lol
no but making on your back after ejaculation can help sperm movement
and masterbating while laying there til u orgasm can help your cervix dip down and let sperm in
@kbogzxo, lol I guess that's how I ended up pregnant lol
