Do not **** single mothers. That is a recipe for disaster. She is single for a reason. She either has bad judment, and chose a bad partner with whom to have a child; or she is mentally unstable, and drove a good partner away, despite his biologicial link to her through their child. Either way, you are risking being trapped by pregnancy with a woman who will make you miserable, and providing for another man's child. The short-term enjoyment is not worth the long-term complications. You say you have a big dick, and nice thighs, you can do so much better.
That is fine, you should just limit them to single, goal-driven women. They are just as likely to want casual sex without the complications of children and relationships as you. And if you have a nice dick and are not a creep, then they are likely to return for repeats whenever the need arises.
The only downside is that since there is a risk of pregnancy, you will need to use a condom every time. You cannot trust a one-night stand to be using birth control or to be using it correctly, so you will need to protect yourself.
That is why it is better to build a stable of trustworthy partners that you can rotate. It is how I am able to have a different guy for every mood, and can have sex whenever I want, and not have to worry about STIs.
You are just under 8 inches, and have muscular footballer thighs. There is no shortage of women who want that between their legs. Get a stable of fine women.
Dude, it's not like the gay game. They have periods and hormonal things, and obsessions about what they think is cute.
Ever gone shopping with a woman? It's like going to a museum of dresses, jewellery and whatever other crap they can put on their body only to not buy anything or cry if it doesn't fit or go with something else they own.
In fact, the part for me is always the coffee/lunch break and even then it's never a guarantee I'm going to get laid because women aren't as horny as men or have some stupid excuse to leave.
I see this all the time with my straight guy friends. Because they are not attracted to men, they often do not recognize the qualities that make a man attractive. And by extension, they often do not recognize just how many of those qualities they possess.
Because of this, they often do not have a lot of confidence, date beneath themselves, and accept treatment they do not deserve. Men in general are more attractive than they think, and you in particular have desireable qualities others do not. Do not sell yourself short.
Women are just as interested in sex as men, they are just more difficult to sleep with the first time. But after that, repeats should be easier, especially if you give them a reason to return.
