Have one available and ready to put on before you fool around or cuddle or anything. When both of you are ready to have sex during the foreplay, then hurry and put the condom on. since you are probably inexperienced with this, you both may need to continue the stimulation process while you are putting it on correctly. My ex used to take so much time putting one on and then I'd loose my urge. So we would each stimulate ourselves while he put the condom on so that we would both stay ready to have sex
