I'm straight and love women but hate condoms; unfortunately if you want a varied sex life then they are a necessary evil. I know the feeling when I meet a new partner: we're both pretty excited and I'm as hard as a rock, she's obviously getting wet, we're tearing each other's clothes off in anticipation, out pops my rod, her eyes light up, etc etc. I always keep the right-sized condom easily available, open the pack quickly, put it on myself and go straight in without delay. That's one scenario. However there are plenty of occasions when the foreplay is long, and the condom ritual can certainly be off-putting and affect my erection. There's no single answer to this problem. I guess one way to avoid disappointment is to get her to put it on while I finger her.
