I once told girlfriends, "You can tell how good of a lover he will be, by how he kisses you." Most recently my tune is "You can tell how sexually compatible he will be by the way he hugs you."
Sex is pretty important to me. It's a deal breaker. If he's not good in bed, well then, it is going to be over sooner rather than later. Trouble is, to find out whether he's appropriately equipped for you, or not, you have to fuck him. And, if he is one of those guys that thinks you are cheap for having sex with him early on, he'll just cast you aside. So what is a red-blooded American girl to do?
Follow my lead, and test him out with his hugs first. A man who leans in and envelopes you with his arms, is sure to be a fantastic love. If he sort of just hangs on, and is in a neutral position, that is a red-flag. Most likely he will have some hang-ups. Now if he leans back, and makes you do the hugging, that is a sign he has selfish tendencies. He may even hold out on you when you really need a good fuck.
Kissing is the next way to determine he will be a good lover, before you actually end up in bed with him. Kissing preferences are very much an individual thing, so I will not go into that here. You decide.
So how else do you determine whether or not he will be good in bed? Press yourself against him so
