Oh you lucky young studs!
Those of us with heart, circulation, etc, probs do need extra help because of the medical condition. Viagra may be an "instant hard-on" but in my opinion Cialis is a better product over a longer period. It's slower but longer acting, so a pill on Friday lunchtime will still be working (for me) on Sunday as well as the Friday night! Unlike Viagra, it doesn't give you the instant erection but... I have no headaches, or an inability to cum because my cock is too rock-hard. I just get "normal", but extended, hard-ons - most satisfying (for all concerned!).
With Viagra, I found that once I'd cum I couldn't normally get him back again (or at least, half-heartedly!), but with Cialis he's there again after 20 mins or so.
Try Cialis instead, if you're "at it" over an extended period (days).
No, it's not just 'outside swinging'... swinging parties know and approve of each other (reasonably), but here there is still the element of 'chance', with the serious dangers (robbery/violence/Police action) removed. It would need a large clientele to increase the 'chance' element, but the element of 'chance' is still there.
But I acknowledge that some people actually WANT the danger element of dogging.... many don't.
The fact that it has been suggested before indicates that it's maybe a good idea for some of us.
It seems to me that what's needed is a PRIVATE dogging area. Private, probably farm, land to which only invited/known guests/participants are allowed would seem to be the answer - No laws broken; all participants safe and anonymous (apart from being 'known' to the farmer); maybe a small 'tip' as an incentive to the landowner (no charges, because that would put it into a different category).
What we need now is a horny farmer or two to come up with some secluded land and SH to formulate an acceptable policy for all to follow.... with invitations to be dealt with by PMs.
A germ of an idea??
