Condoms. Don't -blam!-ing care what excuse you/he/she has. Wear one. Make them wear one. If they don't slap that chastity belt back on. When you put it on, pinch the tip, place it on the head and roll down to make sure it is snug with no air pockets. When removing, encircle the base to make sure that nothing spills and pull the tip. And make sure to lube. Going in dry can break them. Talk to your partner, ask them what feels good and what doesn't and obviously do what pleases them. Foreplay is big, if you don't think it is, go slide down a dry waterslide. Oral sex is great. Make sure to give and receive. Also: The ultimate goal of sex is to get you and your partner off at the same time. It's not a race and using oral to get your partner off after you've finished is a shitty consolation prize. If you're getting close to finishing but they aren't. Think about something else, change your rhythm to cool down.
