Sex Without a Condom

I have been taking tri sprintec (birth control pill) for about 1 1/2 months. My boyfriend and I always use condom, but I have heard having sex without a condom and letting him finish inside of you feels totally different (in a really good way). I’m wanting to try it out but i’m super paranoid about getting pregnant because both of us are both full time college students. Is this a good or bad idea? And what are your tips for afterwards (cleanup wise) /what is it like? THANKS!
