last night my boyfriend and I had sex twice. he pulled out the first time and before he even finished we decided to have a second round. so he pulled out and finished, we then cleaned up and Started having sex for the second time. he also pulled out the second time he came. I'm worried about the Precum factor and/or if anything was still on him. I am on birth control, consistently. I'm considering taking the morning after pill to be safe. if/when I take the pill should I stop my birth control? and if I get my period soon after the pill is taken, should I stop my birth control or continue ?
