No farking way on all three....
Not because I'm worried about STDs and such. I'm afraid it's more to do with my fragile 'man ego.' I'd never be able to feel comfortable and let go knowing they've had copious amounts of sex.
Sex should be a very enjoyable thing....and the pressure to 'perform' would be too great for me to enjoy it.
I know....I'm a sad....sad little man....
