hi everyone,
I have been giving blowjobs for years but I'm beginning to think I need to change my technique..any ideas for something new/interesting I could try? thank!

I always appreciate a new trick or technique to try out. The best advice I could give you is to ask the guy to tell you what he's into. A lot of guys get off on telling you how to suck them.
Apart from that maybe watch some bi lessons porn. Tends to be a milf teaching a sexy young woman how she sucks cock.

go with peehole licking... mmmmmmmmmm

With your hand around his cock, push the loose skin tight against his body. This will expose the nerves around the edge of the head of his cock. Then stiffen up your wet lips and suck hard and moderate pace on that edge of his head. Short head bobs rubbing those lips on that area. Keeping the shaft skin very tight. When you need air, keep pushing the skin tight and grip his entire head with your slick wet palm and twist on his head, tight but slowly. You will have him cumming hard and fast!!

For me it's deep throat, both giving and receiving. Some people have natural knack, some people need practice, some can't do it at all. For me it's the lips around the base of my cock, guy or girl it drives me crazy.

When sucking a dick I also like to incorporate some hand job action, alternate between hand on and hands free. And I add plenty of licking of the shaft and balls, it's good for the visual as well as the feeling. But as was said earlier, it pays to ask the guy what he likes or might like to try!
