Hey, tbh mate I think its really hard using websites to contact women as shows instant low value because it looks like you're too scared to speak to girls in person(Though the girls are there because either they want an ego trip or they want sex/relationship so it is definately possible to get a lay). The best way really to counterract this would be by having lots of pics with you with girls etc. I'm not saying you shouldn't try it but its definately very hard to stand out on a dating site. My best advice is be original, be funny and be the most interesting person on there
