Hey mate.

First things first. If you have a bit of sexual anxiety with women especially a girl you really like. Not getting hard or losing it during the session does happen, especially when you're inexperienced and lack confidence. Most people don't want to talk about it. No shame in going to your GP and asking for a pill in my opinion. Personally I did and it helped me get over that psychological bump with my first relationship. Don't let it be the reason as to why you won't ask that girl you have a crush on.

In terms of rapport, don't get too worried about it. Small talk is small talk. It's a business transaction at the end of the day. Just treat them like a regular person, be respectful and no means no.

Tipping them a little extra or seeing them more than once is likely going to make them like you more. Honestly that's how I got a couple regulars personal numbers, which theyve invited me to go directly to their home to punt.

Again as with majority of the lads here on this forum, it's punting. Don't get involved or even consider making a relationship.
