also, as a fairly nervous but apparently not unattractive dude at 30 years of age (sorry about that but I know for sure I nixed a lot of sexual experiences out of fear, not being ready, or simply pride/shame, which are two sides of the same coin), try to correlate it with how you feeling haning out with other people, especially whatever type or gender people you want to have sex with when you seem them. For one thing, just know that you might be letting fear of judgement cloud you. Sex is really fun. Anyone worth having sex with might or might not react nicely initially to you not being able to get a boner from nervousness for20 minutes, or to you just being a bit afraid. They might be smart and mature enough to know how to tell you it's fine and to then help you out, or wait for another time, or they might not. Either way, that initial encounter isn't a stamp on your 'sexual prowess' or 'likes having sex' uniform for ever. I had my own shit there and the more relaxed I was, the better things go beyond the immediate 10 minutes of 'oh shit, my teen move life' fear, be it that one night or over days, weeks or months. Girls get dry, have periods, get super horny out of nowhere.

tl:dr : don't be afraid. on a chance encounter or with someone you know (or want to know), take it from a very fearful person with a hot girlfriend: it's intimidating. Own that, and look for empathy and sexiness together. It might take time, might not. I've had long-term, amazing girlfriends who never enjoyed sex, were shaped oddly, or just had habitualised certain modes of dealing with it, just as I had. Tiny bit of love and making out and patience and wanting them to feel good, and there's zero to fear with any person with a heart. A scared man can lose a lot through fear of being modern and aware of himself enough to act like it, but can also gain some shit that a lot of men in history had no access to, which is partnership, however transient. Go for that and any fear will go, and turn into momentary, 'aw shucks but hey, let's try in 10 minutes or days, and I've the same shit from time to time' scenarios. Sex is amazing once preconceptions and ego go out the window and.
