So me and my boyfriend had dry humped today without our under garments on. And he had precumed before but he washed it off and pat it dry before doing it. We did it cus the condom wouldn't work whenever he tried to put it on he'd lose his hard on cus it's both our first times. I still took a plan b pill right after. I'm thinking of starting contraceptives. Thoughts? Is it safe? Regulates periods? Cus I do get irregular periods at times
