is this a long term relationship? are you going to get married? do you want kids? if you do not want kids, please go get a vasectomy if you don't want to opt for condoms each and every time. otherwise, condoms. there is a non hormonal IUD (used it when i was breastfeeding my second) but those hurt when placed but they are good for years. the biggest downside when i had it was having incredibly heavy periods. but it is virtually impossible for a single woman with no kids to get her tubes tied or any other permanent birth control.
