So I've been sexually active with my boyfriend for 3 years I'm 23. For the first couple months we used condoms but then we just stopped I've never had birth control. I've heard a lot of my friends tell me it changes their sex drive and makes them gain crazy amount of weight. If you are on birth control can you tell me how or if it effected you? Unprotected sex for 3 years now and not pregnant yet. We wouldn't mind if I got pregnant we are happy and in love and own our house already.
